Google SAML Provider says “Not Found” when logging out - on new update

I was running the 2024.10 version of authentik when this happened.
Our boss encountered the issue of a message “Not Found” when they tried to sign out of google. When they would go back to google, it would still have them signed in.

has anyone encountered this, and if so, what did you do to remedy this? I had to roll back to the August update of authentik to fix the issue for now, since they have important information to keep secure. I will keep investigating for now.

I tried it on another machine, my account and a dummy account, and it was reproducible. Is there a setting that needs changing that is not in the documentation currently, like the new option for logging off?

No files, tests, or entry points are named in the report. Start by reproducing the Google SAML logout flow on authentik 2024.10 and compare it with the August release; done means logout no longer shows “Not Found” and Google does not retain the signed-in session.
