[Bug]: Unable to unsubscribe to remote communities stuck in the Subscribe Pending state

[IanNorris]

Requirements

• Is this a bug report? For questions or discussions use https://lemmy.ml/c/lemmy_support
• Did you check to see if this issue already exists?
• Is this only a single bug? Do not put multiple bugs in one issue.
• Is this a server side (not related to the UI) issue? Use the Lemmy back end repo.

Summary

If you subscribe to a community you no longer want to subscribe to, if the subscription is stuck in a pending state (Subscribe Pending) then there is no way to unsubscribe from it. Clicking the link in the UI does nothing.

This probably happens at the moment if some instances are backed up. I have multiple in this state, for example memes@lemmy.ml without any way to unsubscribe.

Steps to Reproduce

1. Subscribe to a community on a congested instance (eg memes@lemmy.ml)
2. Go to the Communities list and click to show your Subscribed list.
3. Observe the Subscription Pending state
4. Notice there is no way to cancel the pending subscription even though the content appears in the feed

@SleeplessOne1917 This is fixed in >= 0.18, yeah?

[SleeplessOne1917]

@alectrocute I'm not entirely sure. If you want to verify, you can test on voyager.lemmy.ml, which is currently running 0.18.

[IanNorris]

Would I be right in thinking voyager is unfederated? From what I can tell it can't see other instances. I think the issue may have been made visible by lemmy.world being unfederated from beehaw and lemmy.ml which were the instances stuck in the Subscribe Pending state for me.

[SleeplessOne1917]

@IanNorris voyager is not federated.

[IanNorris]

Unfortunately I can confirm that 0.18.0 doesn't fix the issue.

[Gestrid]

Can confirm. My instance, lemmy.ca, is on 0.18.0, and it's still happening. Notably, it's only happening to communities that I sub to on lemmy.ml, though the other instances I sub to probably aren't nearly as busy as that one.

lemmy.ml works for me from sh.itjust.works, but lemmy.world and zerobytes.monster are stuck in the pending state. Posts in the communities I'm trying to subscribe to don't federate to my instance, either, so I don't think it's just an issue with the response to the request.

I believe that these instances may have been unfederated by the network - this is what originally caused this issue for me as my account was on lemmy.world.

[zacharee]

I checked and none seem to have blocked each other. sh.itjust.works has only blocked burggit.moe and lemmygrad.ml. lemmy.world doesn't have sh.itjust.works on its blocklist, and zerobytes.monster has sh.itjust.works on its allowlist.
