Unable to complete the login process due to a backend error

Login to the Fiddler Everywhere 1.6.0 gives this message after a minute trying:


Unable to complete the login process due to a backend error


This is definitely not a user/password issue because bad password tells me just that.  It accepts the credentials initially and can't process whatever on the back end.


What does this mean and how can this be resolved?  It seems silly I can't use an app installed on my Windows 10 Version 1909.


Hey Marc,

Can you please share your application logs? You can find them by using the Help -> Open Application Logs Folder from Fiddler Everywhere. We'll need all the files in the directory for investigation. 
Also, are you working behind some corporate proxy or firewall? Fiddler Everywhere needs access to several *.getfiddler.com endpoints and if for some reason this is not possible, the application will show you the mentioned error message.

Rosen,


Attached are the two log files.


I do have a corp proxy URL I would use if known where/how to add it into Fiddler Everywhere.  This may be the same issue I have with Fiddler Classic where it worked fairly flawlessly until I received this new Windows machine and I hadn't seem to resolve.  Any info how to address the proxy issue for both Everywhere and Classic would be appreciated.


Thanks,

Marc

Hey Marc,

Thanks for the logs. Based on them we have two suggestions what might cause the issue:
- Your PAC script rejects the access to some of our *.getfiddler.com APIs.
- We have an issue with respecting the default proxy configuration during startup of the app,  we are working on it and we'll have it fixed soon, but we need to check if this is causing the troubles on your side.

In order to verify the reasons for the error, can you try the following:
1. Open https://dashboard.getfiddler.com and try to sign in. Is the operation successful? Do you see any errors in browser's DevTools?

2. Open https://api.getfiddler.com/ - do you see a browser prompt to sign in or the page just does not load (note, you will not be able to sign in with your credentials, it is important to see the prompt)? 

If both of them are working, most probably the issue is the one I've mentioned - where some of the requests we execute from Fiddler Everywhere to get information about the user and cloud resources, does not respect the system proxy. The only workaround for it at the moment is to ensure *.getfiddler.com APIs are accessible even without your proxy.

Regards,
Rosen Vladimirov

Both Steps #1 and #2 are a success.  Do you have an ETA when "fixed soon" will be?  In the meantime, I'll look at accessing the *.getfiddler.com.


Thank You,

Marc
