Is this bug report related to this issue?

I did a third test, and it was unsuccessful as well: https://the.socialmusic.network/t/third-test-federating-a-new-topic-from-tsmn-to-wd/472

I have noticed that our #general category is followed by @deadsuperhero's account on We Distribute. Shouldn't there a follower by the category actor? Sorry, I don't know how the NodeBB federation works and this might make no sense.

Also, you say that federation with https://socialhub.activitypub.rocks/ (also a Discourse) works. Which We Distribute category is federating with which SocialHub category?

Mmm, topic creation from TSMN to WD doesn't seem to work.

Also, I edited the post above a couple of times, and the federated post on WD isn't being updated. For what is worth, Discourse posts federated on Mastodon are updated.

Ok, interesting but there is room for improvement.

Yes, but something seems to prevent that new topics are created on We Distribute by the TSMN federation... https://the.socialmusic.network/t/testing-we-distribute-tsmn-federation-take-2/471

Very good! Replies from TSMN to We Distribute work: https://forum.wedistribute.org/topic/15/testing-federation

Let me try to start a new test topic from TSMN again.

Ok, so TSMN is following We Distribute correctly. What about the other way around?
