Lemmy Support

Hello everyone! I'm experiencing troubles with federation with other instance. I get a lot of operation timed out in logs

Caused by:
    0: error sending request for url (https://lemmy.world/u/Ricey): operation timed out
    1: operation timed out, context: SpanTrace [{ target: "lemmy_apub::activities", name: "verify_person_in_community", file: "crates/apub/src/activities/mod.rs", line: 50 }, { target: "lemmy_apub::activities::voting::vote", name: "verify", file: "crates/apub/src/activities/voting/vote.rs", line: 57 }, { target: "lemmy_apub::activities::community::announce", name: "receive", file: "crates/apub/src/activities/community/announce.rs", line: 141 }, { target: "lemmy_server::root_span_builder", name: "HTTP request", fields: "http.method=POST http.scheme=\"https\" http.host=random-hero.com http.target=/inbox otel.kind=\"server\" request_id=5955a024-6b1e-458a-b846-156e14fe5368", file: "src/root_span_builder.rs", line: 16 }] }

I get this from many instances but ping to them works just fine. I can't even add new communities now. I've increased federation workers but to no avail
