Edit: Seems to be working again. Thanks to whomever thanks are due.

When trying in the app I use, Sync for Lemmy, I get a generic error message after a bit.

Thought it might be app related so I tried on the Web version, at lemmy.blahaj.zone, where I get the following error message:

{"data":{"error":"unknown","message":"Request error: error sending request for url (http://pict-rs:8182/image): operation timed out"},"state":"success"}
