Cannot join #html.css:matrix.org from any homeserver #14933

@progval

Description

@progval

Description

#html.css:matrix.org seemingly cannot be joined from any homeserver (tried from e2e.zone, grin.hu, and synapse.test.progval.net)

Steps to reproduce

On either Matrix.org or another homeserver, type /join #html.css:matrix.org

When joined from Matrix.org, the client gets this response: {"errcode":"M_UNKNOWN","error":"Internal server error"}

When joined from another HS (Synapse), here are the logs:
