Based on the images you have provided, it looks like you are hitting the issue with Fiddler Classic (where this forum is primary for Fiddler Everywhere).
It seems that the proxy is inaccessible, so we can't test the scenario on our side. However, there are a few things you could try:
- Stop Fiddler Classic capturing. Go to Options > Gateway and set the Use System Proxy option. Close the application entirely.
- Save your PAC script in the operating system proxy settings.
- Start Fiddler Classic anew and observe if you can access and capture the HTTP/HTTPS traffic. Check if you are still receiving the unreachable error
Proxy Configuration Script specified an unreachable proxy.
Then test the same scenario in Fiddler Everywhere if the issues persist.
- Stop Fiddler Classic application entirely.
- Start Fiddler Everywhere, go to Settings > Gateway and choose the Use System Proxy option.
- Stop Fiddler Everywhere capturing and close the application entirely.
- Save your PAC script in the operating system proxy settings.
- Start Fiddler Everywhere and observe if you can access and capture the HTTP/HTTPS traffic. Check if you are still receiving the unreachable error.
If you are observing the same error in Fiddler Everywhere, please send us the Fiddler Everywhere application logs (accessible through Help > Open Application Logs Folder).

Hi,
I'm using a PAC script as a system proxy. When I save the script address, I get a yellow bar on Fiddler with "The system proxy was changed. Click to reenable capturing". When I access the internet, my system honors the PAC script but I don't see the traffic in Fiddler. When I click on the yellow band and enable capturing, I see the traffic flowing in Fiddler but Fiddler doesn't honor the PAC script.
In the Event Log, I see "Proxy Configuration Script specified an unreachable proxy". Any thoughts on why we are seeing this log? The proxy endpoint(https://azflex.example.com) is reachable and without Fiddler, traffic is flowing through the specified proxy.
But if I were to give the below gateway settings, Fiddler is honoring the proxy endpoint and I see traffic captured in Fiddler.

Any help in resolving this issue is much appreciated. Thanks!
