An unexpected error

Hello, I was using my Stremio + All Debrid setup, and everything was working perfectly until tonight when, on any source and device, nothing works anymore. I get the message on a red background: "An unexpected error, please try again later." I've spent an hour searching for the source of the error and I can't find it. The streaming server's IP address is listed as offline, but I'm not getting any notification of that on All Debrid.

Any ideas?
