I've been having issues with federating with lemmy.world lately. While looking at the logs I see "Domain is blocked" repeating all of the time like this: WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: Domain is blocked

I am wondering if it's an issue with my configuration or have they deliberately blocked my small instance? According to the "instances" view both of the instances should be federating with each other?
