Fiddler Everywhere on Mac is not launching


When I launch Fiddler Everywhere 3.3.1


Nothing happens it tries to start, says loading in the prompt then crashes.


I am trying to do the trial


MacBook Pro (15-inch, 2017)


16 GB 2133 MHz LPDDR3


Catalina - 10.15.7 (19H1922)


It looks like it takes about 2-3 minutes to startup...still fails

I am also on a company VPN, could be related.


Now working, seems to be hit or miss.  Enterprise proxy and vpn messing up the app.  But I think I have a work-around.  Thanks for info.

Still getting error, sending logs to support at getfiddler

It looks like this is resolved.  I don't know what specifically fixed this. Possibly a reboot of the machine.  Not sure.  I don't need to send the logs.

While Fiddler Everywhere is not compatible with some VPN tools, it does not makes sense that it fails to start. Most likely, you will see a login error due to some endpoints being unreachable through the VPN, but the application remains active. Check if you have access to the required endpoints from our prerequisites. Alternatively, you can also use the following endpoint to verify that you can access the Fiddler Everywhere endpoints: https://fiddler-backend-production.s3.amazonaws.com/connectivity-test/check-fe.html


You can also privately send us the Fiddler Everywhere log files to support at getfiddler.com. Refer to this KB article on how to access the logs manually. Note that these logs might contains sensitive personal data, so do not post them in public forums.
