Failed to select initial bridge for participantRegion=null

[renepardon]

I set up one shard (shard0) on DigitalOcean. So far so good but I can't start a conference - everyone see their own video only. Jicofo complains about that:

Jicofo 2021-07-30 08:30:34.848 WARNING: [110] org.jitsi.jicofo.bridge.BridgeSelectionStrategy.log() Failed to select initial bridge for participantRegion=null
Jicofo 2021-07-30 08:30:34.848 SEVERE: [110] org.jitsi.jicofo.JitsiMeetConferenceImpl.log() Can not invite participant -- no bridge available.

Whereas Prosody successfully tells me the people who joined already:

muc.live.myproject.de:token_moderation                              info    total joined : {"jid":"4d93e691-268c-4ddc-bba4-34c5908be11c@muc.live.myproject.de","room_members":["Tobias Z.","René P."],"type":"joined"}

[congthang1]

are firewall open for UDP ports on all nodes?

[renepardon]

HI @congthang1

and for Inbound they are also all set - looks like DO does this automatically for me ;)

[congthang1]

No they are not default open for all inbound ports, need to modify it. And if you want to automatically add to all new nodes you can use tag instead of instance on the selection of droplets

[renepardon]

I did so on all nodes but nothing changed ;(

[congthang1]

Restart all containers after that. Remember jicofo restart later than web to make sure prosody is on before it start

[renepardon]

Looks like I replace a few things which I shouldn't. Works now - thanks for this amazing setup :)
