I upgraded and tried to login today, and it failed "logging in" time and again.

I name it "logging in" as I don't know what the program is exactly doing - so for me as the user it is logging in.  

The program each time does not show me anything but a new login dialog, which then shows me a browser, I'm logging in in the browser with Google, that seems to work as the browser says I should proceed in the app, and then the app just restarts that process after a few seconds...

Then I found the following in the logs:

Hi Nick,  thx for your quick response.

I wlould like to provide you with the best and fastest feedback :)

I just clicked the link with the required login endpoints.  It says:

Provide an active Internet connection with access to the following URLs:

  https://*.getfiddler.com/

  https://*.amazonaws.com/

How do I do that exactly ?  I understand that something should be accessible, but my browser does not support the asterisk, so I wouldn't have a clue what to access specifically...

When I go to https://getfiddler.com/login-success, the browser shows me 

So I removed the .fiddler folder, as per your suggestion, and tried again.

Same problem.

So then I tried to get in touch with support - I suppose that includes logging in into the website.

There are only options for a limited trial, or for an endless paying subscription.

Did Fiddler move to a paid-only model since the last time I used Fiddler, like a year or more ago or so ?  

Because I did not have an active trial, nor am I already paying for any Fiddler service.

If this is the reason I didn't get logged in, the tool could get me more information, I suppose...

I don't want to start a paid trial for checking if I can log in, so that seems like an awkward support option.

I sent an email, as you suggested, and got the following reply:

Hi Dirk.maegh,

Thanks for writing to the Fiddler support team!

Email support is only available to users who upgrade to a Fiddler Everywhere Pro, Fiddler Jam Starter, or higher tier account.

Alternatively, you can post your issue on the Fiddler community forum for help from the broader Fiddler community.

Regards,

Fiddler Support Team
