I'm sorry to say but Freenode banned the bridge account and banned several accounts of IRC users.
No Lojban channels are bridged to or from Freenode. If you prefer IRC please use irc.libera.chat as the new server address. I can see many Lojbanists already migrated there.
Channel names are the same there: #lojban, #ckule, #jbosnu, ##jboselbau
