AIO - Talk Container does not start

I use the AIO docker container. After the update to version 7.5.1 Nextcloud container did not start anymore. When I deactivate the Talk container it starts again. In the log file of the talk container I get the following error:

Message: Server error: POST http://localhost/v1.41/containers/nextcloud-aio-talk/start resulted in a 500 Internal Server Error response:
{"message":"driver failed programming external connectivity on endpoint nextcloud-aio-talk ( (truncated…)

Hi, can you post the output of sudo netstat -tulpn here?

Apparently you are already running a turn server on your server which uses port 3478. That is why the talk container cannot start.

You can adjust the port that the talk container uses by so: GitHub - nextcloud/all-in-one: Nextcloud AIO stands for Nextcloud All-in-One and provides easy deployment and maintenance with most features included in this one Nextcloud instance.

I didn’t know that with AIO I don’t need an own turnserver anymore. Therefore I just removed it. Now Nextcloud starts.


I fear I have changed the STUN- and TURN-Server in the Talk configuration. What is the correct setting for using the provided server of AIO?

You can just delete the config and restart the containers which should automatically re-populate the correct settings again.
