Cannot login

It's the same issue as with this ticket, 

https://community.getfiddler.com/support/discussions/topics/12000025819,  but the solution can't be applied because of different OS.

I' m going to describe the issue brifely here:

Login with google would fail when returning to app, and using email would fail and warning about  possible proxy misconfiguration. But I haven't set any proxy on my mac.

Log also suggests the problem is related to proxy settings.

I have tried to resintall fiddler everywhere , but it didn't work.  It worked if I using my phone as hotspot, and no proxy settings in fiddler either. And if I change back to wifi, it still can't login. What's more confusing is that, I can't make it work anyway today.

Sorry, I didn't check your link on testing network on macos, the script result showed the active adapter is PPPOE, which is very strange. And the proxy for PPPOE is actually set as fiddler default port, after I uncheck the proxy settings, it's working again!  Thank you


Hey Drifeb ,


Thanks for reaching out to us! Could you please share more details about the active internet connection you are using on your macOS? I suspect that your active network adapter is not recognized by Fiddler Everywhere which leads to the issue where we are unable to set the OS proxy. Please try the following:


https://docs.telerik.com/fiddler-everywhere/knowledge-base/test-fiddler-network-access-on-macos


Additionally,  you could also send us the full Fiddler log files so we could investigate further.

I'm using home wifi and no proxy was set. It worked fine before it breaks, no change on the configuration of network.

After a second look at the logs , it seems that fiddler was trying to connect to it's own proxy after launch.

Can you give me a quick fix to get rid of the problem?
