Cookies are erased when opening dev tools on localhost - google-chrome

Anytime I have dev tools open on localhost my cookies are deleted and I am redirected to the login page on every page load which means I cannot use dev tools to debug or get insight into my site. I have localhost setup with a valid SSL cert (self-signed) and the site works normally until I open dev tools. How do I fix or disable this new "security" or setting in chrome?

After lots of issues and trying out many different things I came across this post/answer
When adding a Javascript library, Chrome complains about a missing source map, why?
Turns out that when I opened Dev Tools it would request a CSS map and the request was being sent to a different firewall causing my application to require me to re-authenticate every time this resource was requested. Turning off the CSS source map option fixed the issue

Chrome request not making it to server

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.

Fiddler capturing traffic from a specific process stopped working in Chrome

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.

How to clear DNS cache in google chrome

On Linux Debian 10 (Buster), I am using the http(s) client google-chrome-stable.
I was configuring (nginx) and testing (chrome) a reverse proxy and it got cached using a wrong domain.
I fixed the configuration but it still resolve to the wrong domain.
I have tried to go chrome://net-internals/#dns and click on Clear host cache but that didn't change anything.
I have tried to go chrome://net-internals/#sockets and click on Flush socket pools but that didn't change anything.
I am not working with FireFox, so FireFox can resolve correctly (so does curl).
After about 10 minutes, without restarting chrome. I did F5 (refresh) and it was loading the proper page. I haven't found a manual way to immediatly clear chrome cache.
I am doing devops and I haven't solved this issue for years.
Would love to know how to do one day :O
What happens if you open developer console F12 and then hold down on the refresh button and then select empty cache and hard reload?
Take a look at this gif for an example.

How can I view Google Chrome DNS cache on MacOs Mojave?

I'm wondering if there is a terminal command that allows me to view my google chrome DNS cache on Mac.
Thanks
I have the same exact problem. Chrome is resolving a URL to the wrong IP, all other browsers resolve to the correct one. Upon inspecting the net-internals menu it just gives me the option to clear cache. There doesn't appear to be any direct way to see it.
What I did instead is I allowed the website to resolve to the wrong IP, then accessed the developer menu (F12 on Windows), clicked on Network, chose one of the loaded images and clicked the 'Headers' tab. under General -> Remote Address it showed me which cloudflare proxy IP the something.com address was resolved.

How to avoid the "Your connection is not private" screen when developing an HTTP2 site locally?

When I'm developing using Node's http2 library (which only supports HTTPS, not HTTP), when I open localhost in Chrome, I get a warning screen:
Your connection is not private
Attackers might be trying to steal your information from localhost (for example, passwords, messages or credit cards). Learn more
NET::ERR_CERT_AUTHORITY_INVALID
You have to click "Advanced" then "Proceed to localhost (unsafe)". It gets annoying having to do this during development.
I generated a cert and key for localhost use according to the instructions for Node's http2 module. Is there any way to generate them in such a way that Chrome would actually accept them for localhost? Or is there another easy way to get rid of this warning?
(I'm aware of the option of launching Chrome with --ignore-certificate-errors but I'd prefer not to do this for all websites.)
Try the following:
In Chrome, put in chrome://flags/#allow-insecure-localhost in the address bar.
Enable the option that says "Allow invalid certificates for resources loaded from localhost".
Restart Chrome, and it should allow the site.
You can also type thisisunsafe once you put focus on the website
There are two options you can use to get rid of this annoying thing, which are:
Temporarily Disable SSL Warning
You can go to Google Chrome, input chrome://flags in the address bar and press the Enter key to access advanced settings.
In the next step, find the "Allow invalid certificates for resources loaded from localhost" option and enable it. This method is the same as using --ignore-certificate-errors attribute on your Google Chrome shortcut. It disables the SSL warning for all sites.
It's just a temporary solution and I wouldn't suggest to use this frequently.
(I'm aware of the option of launching Chrome with
--ignore-certificate-errors but I'd prefer not to do this for all websites.)
Install SSL On Your Localhost with OpenSSL
You can install SSL on your localhost with OpenSSL. By using this method, your localhost can run HTTPS without any issue at all. The tutorial is quite long with detailed instructions, you can read it at here.
