Server Version#: QTS5.2.3.3006
Player Version#:PlexMediaServer-1.41.5.9522-a96edc606-x86_64
Installed on QNAP TVS872XT
My qnap lost power and shut down over night. After turning the server back on, Plex will no longer load on any client . I tried installing a new version, and there was no change. Everything else on my server seems to function just fine. I don’t know what logs are needed to troubleshoot, but I downloaded a few and attached them here.
Looks like your preferences.xml file is corrupt. its located at /share/CACHEDEV1_DATA/.qpkg/PlexMediaServer/Library/Plex Media Server/Preferences.xml I would stop plex, and then rename it to Preferences.xml.old and restart the server. You will need to re-invite friends to the server if you have shared it.
