VW basically down

I have VW self hosted locally. This morning I tried synching and it failed. Searched and someone said log out and back in again, which I did. When I try to log in with my master PW I get: “an error has occurred. NetworkError when attempting to fetch resource error”.

I can remote to the physical machine and log in there. Where do I go from here. Everything has been working great. VW is in docker on a raspberry pi and the clients are on Fedora 39. Other than a reboot, nothing has changed on the client or PI. When I log into VW web page there is a note: ‘low kdf iterations’. Not sure if it is related.
