Edit: Downgraded to 7.2.0 seemed to fix the problem. I have Diagnostics before and after if anybody wants them. Two for Unraid Diagnostic and two for tailscale. before-after.zip I just updated to Unraid 7.2.1 and before this i updated all plugins. After the reboot i am seeing the same pattern. I have my Plex and Overseer routed via tailscale to a VPS behind nginx proxy manager. Uptime Kuma reports a pattern of up/down/up/down Attached Plugin Diagnostics and Uptime Kuma Logs.
