I am working on Mac and have identical Proxy settings for the System and Firefox browser. However, I am able to see my Firefox traffic in Chrales but I don't see my Chrome and Safari traffic (which use System Proxy Settings). What do I need to do? How can I check the debug this?
Already restarted my browser but it didn't help. I have set and reset proxy settings, but of no use.
One thing to note: I am on a VPN although I don't think this should affect Chrome as Firefox is going through the proxy.
For anyone else using VPN: Charles must be turned on before VPN. So quitting VPN after turning on Charles won't work either.
Also in my case VPN can't be turned on at all.
Did you enable "Proxy-> Mac OS X Proxy"?
Quit your VPN! I was confused almost one year and really upset, i cannot record on my mac.But today i quit my vpn(xx-net) it does works.
Just got caught out with this - the Hola VPN Chrome extension was managing Chrome's proxy settings so it wasn't using the system proxy.
Simply disabling the Hola extension got it working for me again.
I turn off a chrome proxy plugin and it works!
Chrome extension 'SwitchyOmega' can solve the "VPN and Charles cannot turn on at the same time" issue by configure the auto switch option:
Add Charles mode
Add VPN mode
auto switch configuration
Use auto switch mode in Chrome
Desktop applications that set system-wide proxy don't work really well with VPN. I struggled with Charles & Fiddler because I was under a VPN network and almost all the time I couldn't use any of the apps while on my company VPN So I googled for Web Proxy chrome extension and found Requestly.
I am using the Requestly Chrome extension and the chrome extension works well with VPN and it has all the features that Charles has.

I can't intercept requests made by Chrome version 73.0.3683.86 to my localhost site.
Local host site is running on IIS on http://127.0.0.3:80
Burp proxy lister is default one on 127.0.0.1:8080
Interception rules are default one as well
In my LAN settings, "Bypass proxy server for local addresses" is not enabled
When Interception is turned ON and I reload page in Chrome browser, no request is "caught" by Burp, my local site loads and only the external requests are intercepted, such as loading external scripts from CDN.
Also under "Proxy" > "HTTP History" there is only request to external sites, and all requests to http://127.0.0.3:80 are not recorded.
When I reload same page by Internet Explorer 11, initial GET request is intercepted by Burp, as expected. Also "Proxy" > "HTTP History" shows all the requests to local site http://127.0.0.3:80
What is the problem with the Chrome? Thanks!
Found the solution late yesterday. I am using the Chrome extension ProxySwitchy, but it doesn't matter if you use that or the system proxy configuration. The solution works the same way.
You can solve this problem by adding an entry in /etc/hosts file like below
127.0.0.1 localhost
127.0.0.1 somehostname
Now burp will intercept request from somehostname
Which version of Chrome are you using?
Have you tried using the FoxyProxy Chrome extension?
As a workaround, you could modify the hosts file on your machine.
I experienced the same issue when I upgraded from Opera 58.0 to 60.0. I think that this is Chrome related, because I've also experienced it in all other Chrome browsers. Opera 58 utilizes Chrome 71.0.3578.98. Opera 60 utilizes version Chrome 73.0.3683.103. Something was definitely updated in Chrome between these versions to cause this problem to happen.
You have to subtract the implicit bypass rules defined in Chrome (https://chromium.googlesource.com/chromium/src/+/master/net/docs/proxy.md#Implicit-bypass-rules)
Requests to certain hosts will not be sent through a proxy, and will
instead be sent directly.
We call these the implicit bypass rules. The implicit bypass rules
match URLs whose host portion is either a localhost name or a
link-local IP literal. Essentially it matches:
localhost
*.localhost [::1]
127.0.0.1/8
169.254/16
[FE80::]/10
https://chromium.googlesource.com/chromium/src/+/master/net/docs/proxy.md#Bypass-rule_Subtract-implicit-rules
Whereas regular bypass rules instruct the browser about URLs that
should not use the proxy, Subtract Implicit Rules has the opposite
effect and tells the browser to instead use the proxy.
In order to be able to proxy through the loopback interface, you have to add the entry
<-loopback>
in the list of hosts for which you don't want to a proxy. It is a bit confusing, indeed.
Make sure you haven't enabled socks proxy option, it happened with me too and i found the solution when i disabled the socks proxy option, just make sure it's disabled!

This started happening just a few days ago. I can access the site on the same computer in Firefox. Not sure why it is telling me that the site is insecure, but that must be related. I tried ipconfig /flushdns, deleting my cookies, and disabling my firewall but none of those fixed it. Can't find any solutions online either so far. Using the latest Chrome update and Windows 10. Please help!
Edit: Solved my issue by installing this Windows update:

It is possible that you might have deleted trusted certificates from chrome trust store (github CA SSL certificate is issued by DigiCert High Assurance EV Root CA ), where as in for other browsers the trust store must be a different location in your case.
To check above listed certificate present in Chrome trusted store or not, do the following
Open Chrome then Go to Settings => Manage Certificates - Click on it, when Certificates pop-up shows then check at' Trusted Root Certificates Authorities, if desired certificate is not present then import it.
For what it's worth, this is what worked for me:
Open up the start menu and search for and open "Internet Options".
Go to the "Connections" tab.
Click on "LAN settings".
Untick all the checkboxes (there are 3).
Click OK twice and then access https://github.com/ via Google Chrome.
The reason why it works on Firefox is because it has its own proxy settings. Google Chrome takes the proxy settings of the computer.
If you enter the website URL with www, it will work in chrome.
To avoid this you need to add another CNAME without www.
I am using MacOS and I had similar issue of accessing GitLab with Chrome, but no issue with Safari.
What helps me finally is: Setting -> Privacy and Security, and turn off "Use Secure DNS".
If CORS extension has been downloaded and enabled in the Chrome browser then disable the CORS(Allow-control-Allow-origin) extension. It will work..!
If I'm looking for a local/intranet address while connect to a VPN, it works in safari or firefox but many times it will not work via google chrome
example address:
http://help/userui/ticket?ID=14273
Google Chrome takes me to a verizon page like so: "http://searchassist.verizon.com/main?ParticipantID=euekiz39ksg8nwp7iqj2fp5wzfwi5q76&FailedURI=http%3A%2F%2Fhelp%2Fuserui%2Fticket%3FID%3D14273&FailureMode=1&Implementation=&AddInType=4&Version=pywr1.0&ClientLocation=us"
How can I get chrome to realize that I'm looking for a page on an intranet on not to the public web?
Notes:
Using Cisco AnyConnect as VPN client
Chrome version 48.0.2564.97 (64-bit)
OSX 10.11.3
The best solution I've found on OSX so far is to use Safari which is better about detecting VPN pages.
Soon after you've navigated the pages Chrome starts to work as well. This must either be a DNS or caching issue, possible both (I'm no IT master).
Fiddler had worked well on my laptop, but all of a sudden it cannot capture anything from my browsers. I have no ideas about what I have done may cause this problem.
The version of my fiddler is v4.6.0.5, it cannot capture http requests from all of my browsers, chrome, IE and Edge. My system is Windows 10.
I've carefully read the webpage Fiddler not capturing traffic from browsers
However, solutions works well for others do not work in my situations.
I've tried reinstalled fiddler and reset chrome hundreds of times
http://localhost.fiddler:8888/ cannot be found
http://127.0.0.1:8888 returns "This page returned a HTTP/200 response
Originating Process Information: chrome:79748"
I didn't use any filters
I have no extensions on chrome and close all kinds of VPN software.
I've checked 'Decrypt HTTPS traffic'
Anybody knows how can I solve the problem? Thank you!
I found that some of the software's http request is captured. It seems like that only the browsers' requests are not captured.
I temporarily use the developer tools in chrome for replacement(Ctrl+Shift+I, choose "NetWork"). It can capture the requests missed in Fiddler.
Your output indicates that:
Fiddler is running, and
It isn't blocked by a firewall or other software
Fiddler is not set as your system's proxy
On Fiddler's File menu, does the Capture traffic item have a checkmark next to it? While Fiddler is running, if you click Tools > WinINET Options > LAN Settings, what do you see?
Do you have any third-party antivirus software installed? Is this machine under the control of Group Policy (e.g. on a corporate network)?
If you start Chrome like so: chrome --proxy-server=http://127.0.0.1:8888, what happens?
How can I disable internet connection or work offline like Firefox in Chrome? I need to check some errors when Internet is not available.
offline mode is added to Chrome v45.
Developer tools -> Network tab -> Choose "offline" from selectbox.
Offline switcher is a new handy Chrome Extension to do the job quickly. You can toogle to switch between offline and online mode.
The add-on is simple, just to set Chrome proxy to an un-existing point.
Under the network tab, go to the THrottling dropdown where you can select different speeds of web and even set it to be offline. This comes very handy when you are working with service workers and want to test your application in offline mode.

Until Chrome has a feature to disable internet but retains localhost (or local network) connections. The only way I could suggest is to just disconnect the network from the internet manually for your testing.
