Unable to join some matrix.org rooms

[gabrc52]

Tried to join #flameshot-org:matrix.org, and it gave me an error. Try again and look at the Synapse logs to see what happened.

Asked in Synapse admins - https://matrix.mit.edu/#/room/!ehXvUhWNASUkSLvAGP:matrix.org/$Zni-AeKGWdHt28fDNEQAyx_XT4KEsfSAuQ1hSpV1qMc?via=matrix.org&via=libera.chat&via=matrix.breakpointingbad.com

Someone else asked something similar and this was the suggestion

Most oddly enough, I was able to join #nheko-nightlies:neko.dev from uplink.mit.edu just fine...
