Similiar issues still here as well. I can not post to many other communities and subscribing often does not work.

For example i tried posting to !espresso@infosec.pub and the post does not show up on the remote instance but is present here. Commenting on other posts in that community also did not work.

Tried resubscribing and after that it is stuck at pending again. *Tried again a few times to resubscribe and it finally worked. After editing the original post again it was finally posted.

Same issue also with !3dprinting@lemmy.ml. Subscribing does not work and posts are not updating.

Both remote instances seem to sometimes throw a 500 error and seem to be a bit unreliable. Possible that the states got out of sync and posts were refused and no other update is sent?

Retrying at different times seems to sometimes fix it but some are still stuck pending after trying for days.
