Hello! I am working through some issues with federation between my own server, https://globe.pub, and all other Lemmy servers.

When I subscribe to a community on a foreign server (e.g. https://lemmy.world/c/world), I get an error saying Activity was rejected by https://lemmy.world/inbox, aborting: Incoming activity has invalid signature.

I’m having trouble figuring out what is misconfigured on my server. Does anyone have advice on how I can resolve this?

Below are my debug logs for a failed subscription request:

    Interesting! I wonder if that should be written up as a bug report, or if it’s by design. I guess I could see both cases. Glad you figured it out though!
