I built a Plex server about two years ago and it’s been running close to constantly since. I access it through my main Windows 10 PC via the webui. I typically keep Chrome tabs open for the main Unraid webui, Plex, NZBGet, Radarr, Sonarr,and Tautulli. The other day, the webui tab appeared to time out after sitting untouched for a few days. I refreshed it and it prompted me to log in (which it doesn’t typically do) and then it wouldn’t accept my credentials, which I know are correct. The other tabs for my Docker containers continued to work fine, so I know the server was still up and running. I messed around with my Windows credentials, cleared my browser cache, tried other browsers, and restarted my PC, but had no luck.
I hooked a monitor and keyboard up to the server but had no signal to the monitor. Eventually, I quick-pressed the main power button which initiated a server shutdown. After a reboot, I was greeted with the log in request, which I still couldn’t get past. I rebooted and tried in the GUI mode, as well as Safe Mode without plugins, but nothing other than GUI mode giving me a message that said something like “Failed to execute login command.” In the non-GUI mode, I can tell a slight difference between when I enter the correct password and an incorrect one. After the correct password it shows me the Unraid version and the number of failed log in attempts before popping up the log in prompt again.
Any help would be much appreciated.
