Change mail server settings to GMail Account with OAuth2 causes Calibre-Web to become unresponsible

[zisco67]

After changing server-type to Gmail Account with OAuth2 verification and clicking Setup Gmail Account as E-Mail Server, Calibre-Web hangs. I did all the necessary configuration as described here, but no success.
Is there a log-level that I could activate to see more in detail whats happening?
Is there an actual documentation of the configuration process in Gmail API?

Environment:
OS: Linux 3.2.40
Python version: 3.10.0
Calibre-Web version: Latest
Docker container: None
Special Hardware: Synology DS215j
Browser: Chrome 99.0.4844.51

The one and only documentation is this one: https://github.com/janeczku/calibre-web/wiki/Setup-Mailserver#gmail

Just saw you're not running a docker container, the answers in this thread may still be useful for you.

I don't get it to work - no consent screen, just hanging.
API-Test via Postman does the job.

Thanks. I had the same problem with my Raspberry instalation. Following the steps in that issue solved the problem
