Unable to log in after restoring from backup. Existing logged-in devices work without issues.

csolisr commented 1 week ago

Describe the bug

After restoring from a backup, it's no longer possible to log in using the standard CAS login flow. Existing accounts with a valid login are still able to use the platform unimpeded, but new devices are unable to log in.

Context

Hardware: Dedicated x86 computer
YunoHost version: 12.0.6
I have access to my server: Through SSH, webadmin, direct access
Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: yes
- If yes, please explain: Recently reinstalled from a backup; using an external VPS to bypass NAT restrictions
Using, or trying to install package version/branch: 1.117.0~ynh1

Steps to reproduce

Restore Synapse and Element from an existing backup.
Open a web browser to your Element installation, e.g. https://chat.example.net .
Click on "Log in", ensure your base server is correct, then click on "Continue with CAS".

Expected behavior

The standard login workflow should commence, using CAS to validate the user's credentials and then returning to Element's dashboard.

Logs

The site redirects in my case to https://azkware.net/_matrix/cas_server.php/login?service=https%3A%2F%2Fazkware.net%2F_matrix%2Fclient%2Fr0%2Flogin%2Fcas%2Fticket%3FredirectUrl%3Dhttps%253A%252F%252Fchat.azkware.net%252F with an error 404 and the message "File not found."

Just found the error, for some reason the owner for /var/www/synapse were set to be element, not synapse. A quick chown solved the issue for me.

Seem to be a bit strange as on the restoration the chown is expected to be done on /var/www/synapse. I can investigate more if you share me the restoration log.

I'll have to search for the restoration log, but I'm not sure if I still have it since it was from last week and it might have been rotated already
