But I couldn't reproduce it a second time...

Hi @schoettl

Thank you for the report! I just tested on Safari in iOS and logged in and out twice without reproducing. I’ll try soon with FF on Linux.

At least it’s good that it can still work, since Android and iOS still function^^

Good night and speak soon👋

Yeah, it's really not a bad one! :)

I tried on FF 100 on Debian Linux and couldn't reproduce it. However, I also do not get the Gitlab authorization screen anymore. I guess everyone sees that one only once. I go directly from the /sign_in screen to being logged in.

So this downloading of the HTML file might be an edge case that only happens for the first login. @schoettl Do you remember if you've actually been logged in on your first try, or did you only get the HTML file as a response and had to try a second time?

@munen Yes, I got this download only the very first time, I signed in with GitLab (after the authorization step)! So it's hard to reproduce...
