Hello,

Whenever i'm opening the "Fiddler 4", it's showing me below warning, and after clicking OK, the application opens:

---------------------------
Loading custom MIME mappings failed
---------------------------
Fiddler has encountered an unexpected problem. If you believe this is a bug in Fiddler, please copy this message by hitting CTRL+C, and submit a bug report at http://www.telerik.com/forums/fiddler.

Access to the path 'C:\Users\xxxx\OneDrive - XXXX\Documents\Fiddler2\CustomMimeMappings.xml' is denied.

---------------------------
OK

Could anyone please let me know the issue here?

Well, once it's open, I'm getting error: " Fiddler - Gateway Connection Failed." while trying to pull the image from docker.

 

Thanks
