If your server is unreachable, attempts to join rooms over federation fail with an obscure error

[richvdh]

If your server is unreachable (so that the resident server cannot contact yours to retrieve your signing key), then attempts to join rooms over federation fail with

No key for with ids in [<key_id>]

I mean, wtf does that even mean?

This is closely related to #4858

Also a problem on my just-installed homeserver. It did join after a few hours, but never loads properly.

@richvdh I have updated #4858 with my additional error message that lead to the error message No key for with ids in [<key_id>]
do you already know, how to fix this error or what does it mean?

[richvdh]

removed reports from unrelated problems. If you need support please take it to #synapse:matrix.org rather than posting on issues which appear superficially related.

I don't see this string mentioned in the source anymore, suspect it may be stale.

The error message went away in #8398
