In my case, it turned out to be a plugin acting up, causing the Unraid Dashboard to load extremely slowly. All other sections of the GUI (Main, Shares, etc.) loaded normally, but my Dashboard took 20+ seconds. Root Cause The Tailscale plugin was in a weird state that was causing the main Dashboard page to wait for its response and ultimately timeout at 20 seconds, evidenced by the Network tab in Chrome DevTools Solution Deleted & reinstalled Tailscale plugin
