I am trying to record a user flow in chrome browser but I am getting the following error:
Although I have added a recently generated Certificate before recording and I am able to record the flow in Firefox.
Here in chrome, I am getting exceptions that:
(I tried by clicking on Advanced --> proceed but the same message comes again)
This is my chrome setting:
JMeter Setting:
Any solutions for this?
You need to install JMeter's certificate in Chrome, see:
Manage Certificates
How do I manually install the Securly SSL certificate in Chrome?
JMeter documentation on HTTP(S) Test Script Recorder
Installing the certificate in Chrome or Internet Explorer
Both Chrome and Internet Explorer use the same trust store for certificates.
Browse to the JMeter launch directory, and click on the file ApacheJMeterTemporaryRootCA.crt, and open it
Click on the "Details" tab and check that the certificate details agree with the ones displayed by the JMeter Test Script Recorder
If OK, go back to the "General" tab, and click on "Install Certificate …" and follow the Wizard prompts
Also be aware that there is easier way of recording a JMeter test using Chrome - JMeter Chrome Extension, in this case you won't have to worry about proxies and certificates

I have a Windows 2016 Server with IIS 10.0.14393.0 installed that is maintained within an isolated VM environment. (The entire VM environment is isolated from the real-world.)
The web server is configured with three websites through IIS, and each website is assigned a dedicated IP. The contents in each of these websites is a single "hello world" html page that can be accessed via a browser from from my development workstation using Microsoft Edge, but I cannot access these pages using Chrome. The simple hello world html page was created only to assist in troubleshooting this issue.
The error received in Chrome is ERR_TIMED_OUT and based on the IIS logs, the request is never reaching the web server. IIS logs do indicate the request/reponse when accessing using Edge.
From my workstation, I can successfully ping the web server, traceroute output does not indicate any unexpected hops, etc. From all indications, the problem appears to be isolated to Chrome and only when accessing the sites on that server. I have other servers (W2016 and W2019) in the real-world with a similar configurations and real applications deployed there that work as expected with any browser.
I am using the latest Chrome Version 105.0.5195.102 (Official Build) (64-bit) and can access other web based content within this VM environment using Chrome, just not on that one server.
I am almost to the point of deleting that VM instance and starting over so any ideas/suggestions are appreciated.
The error received in Chrome is ERR_TIMED_OUT
This is a communication problem indication that there is a problem with the user's local network connection. It can appear when your internet is too slow or your connection is taking too long, or the page or website you are visiting may be too busy, or when the website in question is not set up correctly, or even if the website is trying to perform more than your server can manage.
I'm not sure if you've seen the following methods, but you can try.
Method 1: Browse in Incognito Mode and Remove Extensions.
You should first browse the website in incognito mode to check if you
can open the website normally, if so then the culprit of the
ERR_TIMED_OUT error may be your plugin or extension. Therefore, you
need to enable extensions one by one to check for errors, and if there
is an error enabling an extension, you need to remove it from your
browser.
Method 2: Delete the Default Chrome Folder
Press Win + R keys at the same time to open the Run
Type %LOCALAPPDATA%\Google\Chrome\User Data\ in the box and click OK.
Close your Chrome if it is opened.
A new window pops out, find the folder named Default. Backup the folder anywhere else, then right-click the folder to choose Delete.
After you have deleted the folder successfully, open your Chrome and
then visit the webpage again that you searched before to check if the
error still appears.
Method 3: Update Network Drivers
If your network driver is out of date, you may encounter ERR_TIMED_OUT
errors. Here's how to update network drivers.
Right-click the Start button to select Device Manager.
Scroll down to find Network Adapters and click on it to expand it.
Right-click on your network device and select Update Driver.
Select Search automatically for updated driver software option to start to search and update your network driver to a new version.
After that, restart your computer and open the sites again with Chrome
to see if you can open them.
Method 4: Disable Firewall & Antivirus Software
Sometimes, your firewall or antivirus software may cause trouble.
Therefore, you should try to disable them and check if the problem can
be solved. If you find it helpful to disable these programs, you can
check the firewall settings. Allow Chrome to connect to public or
private networks. If it doesn't work. Permanently delete these
programs, and then use other antivirus software or firewalls.
Method 5: Check Hosts File
When you meet the ERR_TIMED_OUT error accessing a specific website,
you can check the Hosts file to see if the website has been blocked.
Here is the way to do that:
Press Win + E keys at the same time to open File Explorer and then go to the Local Disk C: > Windows > System32 > Drivers > etc.
Open the host file with notepad. If you see the web address that you cannot visit, delete that entire line from the host file and save.
After that, open the Chrome and see if you can open the specific
website.
Method 6: Reinstall Chrome Browser
If none of the methods above fix the ERR_TIMED_OUT error, then you
should try reinstalling Chrome. Here is the tutorial:
Press Win + R keys at the same time to open the Run box, then type appwiz.cpl and click OK to open a new window.
Find Google Chrome in the list, and then right-click it to choose Uninstall.
After uninstalling Google Chrome successfully, you also need to delete its leftover files. Open the Run box again, then type %appdata%
and click OK to open a new window.
Find the Google folder and then right-click it to choose Delete.
Go to Google Chrome’s site to download the latest version of the browser, and then install it.
The above methods are from the web article. To avoid link being unavailable, I have also presented the details. I am not sure if the above methods can help you, but I hope you can solve the problem soon.
I've been trying to generate a custom client certificate on Chrome OS for things like VPN.
No matter what I do, I keep getting that chrome.enterprise.platformKeys is undefined.
I've been creating test extensions in Developer mode on my managed Chrome OS machine. I see on the documentation page here it says:
Note: This API is only for extensions pre-installed by policy.
How can I properly use this API, if I want to test apps in Developer mode?
Open Chrome and navigate to google.com
In Fiddler use the "Any Process" button to select that Chrome tab
In Fiddler the "Any Process" button changes to something like "chrome: 11788"
In the Chrome tab search for something
I expect traffic to be captured by Fiddler but no sessions are displayed. If I use "Any Process", traffic is captured from all applications.
The "Use Filters" checkbox is unchecked in the Filters tab.
I uninstalled and reinstalled Fiddler.
I have the latest version installed.
What else could I do?
Modern versions of Google Chrome use separate process for making requests; so the process of the main window, detected by the 'Any Process' tool, is different.
The team is considering a fix, but it is currently not implemented, see "Target Any Process" feature no longer working with Chrome.
Possible workarounds meanwhile are:
Use other filtering functionality - e.g. capture a request from Chrome, and from the Sessions view choose right click -> Filter now -> Show only process=<process number>.
Filter everything else. In Fiddler, uncheck Tools -> Options -> Connections -> Act as system proxy on startup. Then Start Chrome with manually specified proxy settings, pointing to the port on which Fiddler is listening:
chrome --proxy-server=http://localhost:8888
This way the only captured traffic will be from this instance of Chrome.
Detailed version: Why Fiddler's Process Picker tool doesn't work with Chrome anymore
Brief version: For security and performance reasons Chrome now handles network requests through a separate network service. So when you are pointing the 'Any Process' tool of Fiddler on any Chrome window/tab, you are actually pointing to the UI (browser process) of Chrome browser.
There is one quick workaround for this:
Navigate to chrome://flags/#network-service-in-process in your Chrome browser. You would see Runs network service in-process and its value would be set to Default.
Change the value from Default to Enabled. By doing this you are telling Chrome to handle network requests from the browser process which also handles the UI.
Restart Chrome. You should now be able to capture network requests by pointing the Any Process tool on any Chrome tab.
Once you are done with your development activities do not forget to set the flag back to Default. This would give better performance.
NOTE: At the point of writing this, I am using Chrome 84.
I want to use fiddler to monitor api calls made by my browser when it visits some pages.
The technology - Fiddler 4.6x, Chrome 56, Firefox 51, Windows 7 64 bit.
The problem - Fiddler does not work with chrome. When I open any page on chrome, I get the error "Your connection is not private: Attackers might be trying to steal your information from website (for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID". FYI, I easily fixed a similar issue with firefox.
Solutions I tried that failed -
Four hours of google and stack overflow did not give me any solutions.
Convert the fiddler cert to pk 7 ??? format.
Import fiddler cert into chrome. Also, grant the cert all kinds of advanced permissions.
Install the fiddler cert with admin rights on windows, by "running" it.
Run chrome and ignore cert errors.
Regenerating the fiddler cert and restarting fiddler and browsers as given in the official fiddler book.
In 2,3 the cert never appeared in trusted cert store, but appeared in personal and immediate cert store. In 1, nothing even happened. Please tell me how I can make this work. Any links to the basics of all this would help.
I was facing similar issue with Fiddler v4.6 and followed these steps:
Fiddler 4.6.1.5+
Click Tools > Fiddler Options.
Click the HTTPS tab.
Ensure that the text says Certificates generated by CertEnroll engine.
Click Actions > Reset Certificates. This may take a minute.
Accept all prompts
Fiddler 4.6.1.4 and earlier
Click Tools > Fiddler Options.
Click the HTTPS tab
Uncheck the Decrypt HTTPS traffic checkbox
Click the Remove Interception Certificates button. This may take a minute.
Accept all of the prompts that appear (e.g. Do you want to delete these certificates, etc)
(Optional) Click the Fiddler.DefaultCertificateProvider link and verify that the dropdown is set to CertEnroll
Exit and restart Fiddler
Click Tools > Fiddler Options.
Click the HTTPS tab
Re-check the Decrypt HTTPS traffic checkbox
Accept all of the prompts that appear (e.g. Do you want to trust this root certificate)

I used these two stack overflow posts -
https://superuser.com/questions/145394/windows-7-will-not-install-a-root-certificate
https://superuser.com/questions/647036/view-install-certificates-for-local-machine-store-on-windows-7
I don't know what is happening. One of these posts worked and I got the fiddler cert into the trusted store. But, fiddler still cannot decrypt many websites https traffic, especially that of google.
After I reinstalled fiddler and did what Abir suggested Fiddler still didn't capture any traffic.
In my case it stopped working because I installed a chrome extension named Tunnel Bear, uninstalling the extension solved it for me.
Firefox has its own certificate store so I assume you just installed the DO_NOT_TRUST... Fiddler root cert there and everything worked. Pretty much you should do the same with Windows certificate store in order for Chrome to work. So make sure you remove all the fiddler certificates you previously generated and regenerate.
if fiddler do not capture chrome traffic, one solution is checking extensions. in my case i use zenmate vpn. when i disable this extension, fiddler capture all traffic in chrome
I am able to access a URL in Chrome 36 and IE8 but in Chrome 39 or 40 or Firefox 35 it throws the error:
Unable to make a secure connection to the server. This may be a
problem with the server, or it may be requiring a client
authentication certificate that you don't have.
Error code: ERR_SSL_PROTOCOL_ERROR}.
It seems that it is an issue related to the SSL certificate. How can I fix this?
Google announced that they would begin removing support for SHA-1 cryptographic hash algorithm beginning with Chrome 39. According to Google:
HTTPS sites whose certificate chains use SHA-1 and are valid past 1 January 2017 will no longer appear to be fully trustworthy in Chrome’s user interface.
There are several sites which can provide detailed analysis of your SSL certificate chain, such as Qualys SSL Labs' SSL Test.
Google Chrome does have a highly risky command-line option --ignore-certificate-errors which might bypass certain certificate errors. Be aware that ignoring certificate errors puts all of your SSL traffic at risk of being eavesdropped on.
It's also possible that this is a new bug. Google switched from using OpenSSL library to it's own "BoringSSL" library in Chrome 38. To report a bug in Chrome visit chrome://help/ and click "Report an issue".
Try this. In Chrome, enter "chrome://flags/#enable-quic" without the quotes as a URL. CTRL + F to search for "quic", at which point you'll find...
Experimental QUIC protocol. Mac, Windows, Linux, Chrome OS, Android
Enable experimental QUIC protocol support. #enable-quic
Turn that to disabled, and let it restart your browser when prompted below.
Go to Windows Firewall, click on "Restore Defaults", then again. The problem should be fixed.
For me this issue resolved when I turned off my Antivirus Browsing control.
First check that in :
Internet Explorer- go to tools/internet options/advanced in the settings box, scroll all the way to the bottom and select Use TLS 1.0 and it will fix the problem.
SSL 2.0 or 3.0 and these are should also be selected.
Google Chrome-Click "wrench" sign on the tope right of it.Click Options then Under the bonnet in network click Change Proxy Settings and follow the steps above as in Internet Explorer.
If this didn't work try the following steps:
Unhide all the files and folders.
Then go to C:\Windows\System32\drivers\etc\hosts.
Right click on hosts file,then click properties. Then click security tab. After that click edit.
Here,click system and you have to check on allow full control and uncheck deny.
Click OK and then OK.
Now delete the hosts file.
