My issue might be related.

My dendrite runs on FreeBSD.
Clients: Electron, Cinny

When joining public room at Matrix.org I see the same error log on server as OP.

As the result of that issue I believe is inability of my clients to search past history on freshly joined rooms as history search are POST requests to my home server, not to room owner server.
