OAuth fails on all browsers

[Fabulous2805]

Attempting to setup some profiles that upload to Google Drive, this is something that I had done successfully for many years before, but this time I install Syncovery 10.15.10 on a new computer.

I attempt to setup the Internet Protocol Settings and when I set Protocol to Google Drive and click on the folder icon to choose the Container, I am taken (as expected) to Google's OAuth interface on my default browser. I go through the OAuth steps but at the final step instead of returning to Syncovery the progress indicator spins and spins and makes no progress (see screenshot). This is the URL:
https://accounts.google.com/signin/oaut ... gInDzOsCUA

I eventually close the tab and go back to Syncovery and on the Waiting for Authentication I click Cancel and then see 3 errors in succession (see 3 more screenshots). It doesn't seem to matter how long I wait, I once waited around 30 minutes and there was no change, I still had to cancel.

I have tried this on Google, Firefox, and Edge on Windows 10 (by setting them as my default browser before each try). No differences between them. Same result if I manually run the profile in foreground. This is quite a problem for my use case. Any ideas would be greatly appreciated.

Here's the OAuth window screenshot. This is what I see when it just sits there with a spinning progress indicator doing nothing.

Attached is the most recent log (redacted). Here's the most important section (I think):

Hello,
this is probably a Firewall or security software related issue.

At the end of the OAuth process, your browser needs to open a localhost page, which is actually a small web server internal to Syncovery.

The URL looks similar to this:
http://localhost:8889/?state=profile&co ... xxxxxxxxxx

This URL is used to pass the authentication code to the Syncovery app.

So you need to make sure that your system allows this.

If you can't make it work, there may be workarounds, but maybe you have an idea how to allow it?

That was it! My firewall was blocking syncovery.exe and it worked as soon as I unblocked it.

Thanks Tobias for the help and for making such great software
