Hi, I see following errors in my lemmy logs on my own instance lemmy.rimkus.it:

and when I try to follow a peer tube instance I see:

lemmy_1 | 2022-07-05T08:07:05.628234Z INFO Websocket Request{trace_id=00000000000000000000000000000000}:perform{self=FollowCommunity { community_id: CommunityId(3), follow: true, auth: Sensitive }}:send:send_lemmy_activity: lemmy_apub::activities: Sending activity https://lemmy.rimkus.it/activities/follow/40d7fc09-90fd-45bb-9353-aa45292dc3ce lemmy_1 | 2022-07-05T08:07:05.632872Z INFO Websocket Request{trace_id=00000000000000000000000000000000}:perform{self=FollowCommunity { community_id: CommunityId(3), follow: true, auth: Sensitive }}:send:send_lemmy_activity: lemmy_apub_lib::activity_queue: Activity queue stats: pending: 0, running: 1, dead (this hour): 0, complete (this hour): 0 lemmy_1 | 2022-07-05T08:07:05.634677Z INFO lemmy_apub_lib::activity_queue: Sending https://lemmy.rimkus.it/activities/follow/40d7fc09-90fd-45bb-9353-aa45292dc3ce to https://mp-tube.de/video-channels/news/inbox lemmy_1 | 2022-07-05T08:07:05.791886Z WARN background_jobs_core::processor_map: Job errored: Processing(Send https://lemmy.rimkus.it/activities/follow/40d7fc09-90fd-45bb-9353-aa45292dc3ce to https://mp-tube.de/video-channels/news/inbox failed with status 403 Forbidden: {"type":"about:blank","title":"Forbidden","detail":"Invalid signature","status":403,"actorUrl":"https://lemmy.rimkus.it/u/ravermeister","error":"Invalid signature"})

are they related? does lemmy use public/private keys for a user? and are they somehow “broken”?

would be really cool if someone could help to investigate. By the way I use the Installation Guide for Docker and already dropped the old db/pictrs data and re-created my instance with blank data folders. But the errors stay the same.

Thanks in advance :)
