Hi there! Looks like you linked to a Lemmy community using an URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !fediverse@lemmy.ml
Wonder if there is a library that could handle the detection part? I can try and contribute if one doesn't exist
Could also consider persisting the instance software to a local (sqlite?) database to save additional requests whenever a message comes in from a known instance
