Authentication not working after a recent update

(Mathieu Comandon) #1

I have a Discourse instance that has been working nicely for the past few months, it’s using a standard Docker setup and is behind an Nginx reverse proxy. (hosted here: ). The Docker container doesn’t use SSL, HTTPS is handled by the Nginx reverse proxy with a Let’sEncrypt certificate.

I have recently received complaints from users not being able to log in and after logging out from my account, I’m unable to log in as well. I’ve tried the /users/admin-login method for logging in an admin user but this isn’t working either.
I had suspected that the problem would come from an issue with SSO login, which I have disabled for the time being and the problem persists.

Here’s what shows up in the logs when I try to log in, no errors whatsoever, the user is just being redirected to the home page without being logged in.

Again, this is a completely new issue. The Discourse instance was working flawlessly a few days ago. I’m running out of ideas of what could be causing this issue and I’m hoping someone here will know :slight_smile:

This happens when the reverse proxy isn’t configured properly.

Please try to add the necessary headers:

I was indeed missing the line

proxy_set_header X-Forwarded-Proto https;

It’s now working again, thanks a lot!!
