Any others clues ?

Thanks.

try restarting services as per following order:

https://docs.zextras.com/carbonio-ce/html/install/scenarios/single-server-scenario.html#step-9-enable-wsc-ui

systemctl restart carbonio-message-broker
systemctl restart carbonio-message-dispatcher
systemctl restart carbonio-ws-collaboration
systemctl restart carbonio-videoserver

Check the journal log of services: i.e.

journalctl -u carbonio-videoserver

I'm on Ubuntu 22.04 LTS and installed a fresh Carbonio CE v25.3.0 (on single node).

# su - zextras -c "zmcontrol -v"
Carbonio Release 25.3.0

Everything is working well except the chat and video call features. When I try to write a message to another user I got this in the ws-collaboration logs :

25-03-2025 15:56:38.126 ERROR c.z.c.c.c.logging.ChatsLogger  : An error occurred on /rooms 
 at com.zextras.carbonio.chats.core.infrastructure.messaging.impl.xmpp.MessageDispatcherMongooseImpl.createRoom  
 Error while creating a room: [{"path":,"message":"Unexpected MUCLightAdminMutation resolver crash","extensions":{"code":"resolver_crash"}}]

And the message stays as "Pending". The other user is considered as "offline" although he is correctly connected. If I refresh the page, the chat disappears and no conversation is present.

Everything seems OK :

● carbonio.service                                   loaded failed failed  LSB: Carbonio Services

I need to restart it like :

systemctl restart carbonio

But the chat and video is still present.

Is someone able to help me ?

Thank you.
