Sorry for the general nature of this request, but I have no clue about most of this stuff. I had Octopi up and running for several months without problems. Today I received a message about updating the Filament Manager extension so I downloaded it and tried to install it. Immediately when I tried to install something broke and I can't reach the octoprint server with either the IP address or octopi.local
From memory I was running version 1.4 I have tried unplugging power and restarting to no effect. I have removed the SD card and verified that the network SSID and password were still correct to no effect.
Here's what I see when trying to connect via IP address, and I have no clue as to what any of this means or how to fix it. Any help is much appreciated.
