@feditips It happens mostly wenn I open a post to see all replies, then the connection to the remote db of another instance hangs. It is thereofre my assumption that it is not a problem of my instance, which I chose exactly for that reason: size, and proper funding. with a noticeable dev and support team.
the error messages appear on the left side like balloon tips, unclickable and without an error code or similar. the message disappears within seconds.
