Description

I've setup Gitea on an AWS instance where I'm running it as my user on port 3000. I am accessing it via an Apache reverse proxy running on the same host via SSL. Everything so far is working splendidly but when it came time to add MFA to my account, the server responded with a 500 error, and this trace appears in the Gitea log:

It's a dead end at this point.

I'm confident the Apache reverse proxy is setup correctly, but who knows. If this helps, the site can be reached here: https://ceregatti.org/git

Please let me know if there's any other information that could help.

Thanks for the great product! Loving it so far!

I tried this over the course of a few days and experienced the same error every today. Today, after having changed nothing, hoping to add the browser request to this ticket, it simply worked. Now not being able to reproduce this, I guess I'll just close the ticket. Sorry for the trouble.
