As the title says… I moved my lemmy instance from one host to a new host. The domain remains the same.

Initially, I just started up a new lemmy instance and repointed the domain, as I’m the only user I care about on my instance at the moment.

I have incoming federated content, which seems to be fine. But if I respond to a message or post a new message on a federated community, it never shows up outside my server.

Thinking there may be some sort of AP ID that is unique to my install, I copied over the entire Postgres database to my new instance and restored from there. Everything came up as expected and everything works, but the same problem remains.

I’m not sure how to even diagnose what’s going on.

Can anyone tell me what might be happening and how to fix it? Everything seems to be working just fine as it should, content is coming in… but if I post anything, nothing seems to go out to the wider Fediverse.

I’m ok with blowing everything out and starting from scratch, but that didn’t seem to work, either. Everything comes in just fine, even if I send myself a PM from another instance, it shows up immediately. Replying to that PM, though, and nothing goes out.

I don’t quite know what to do.
