Missing server to missing user

I seriously doubt it is related to cloud flare. A lot of people have had issues with running jellyfin on Windows for the last couple weeks. I have no way to confirm this, but I suspect that this month's windows update broke something. The way a lot of people resolved this is to go into the Jellyfin Program Files folder and set the jellyfin executable to always run as admin. Or right click on it and run as admin.

All your databases, config, and cache should have been in C:\ProgramData\Jellyfin. I've never tried this (on Windows or Linux), but it should have been as simple as restoring that directory.
