I’ve been trying to use Matrix to replace sites like Discord or Slack. But it seems that if a user creates an invitation-only room in a server, then invited users who are registered on other servers get errors when trying to join. Not very useful error messages either: “Failed to join room”. (In my case, I tried creating accounts and rooms at nitro.chat and then at converser.eu, but friends registered at matrix.org don’t manage to join).
Quite a let-down. Anyone who’s facing the same problem and has maybe managed to solve it?
What are some of the popular Matrix clients that you’ve seen have this problem? And are they open source?
I’ve been curious about Matrix for a while as a potential Discord replacement, but haven’t actually tried it. Might be interesting to check it out and see whether I can contribute to one of the clients somehow.
I’ve only ever used Element for Android. The source is here: https://github.com/element-hq
