Bug description

OS: ubuntu 22.04.4
Nextcloud: Hub 8 (29.0.0) official docker image
Talk: 19.0.0 No additional servers are used.

If has_internet_connection in config is set to false, Video and audio are not transmitted when using the video conferencing and screen sharing functions within the talk app.

I am running nextcloud in a closed environment and have confirmed that when the above setting is set to true, video conferencing and screen sharing can be done successfully without requiring any resources on the Internet.

Steps to reproduce

1.Install NextCloud and Talk apps
2.Disable Internet connection with the following command
　　php occ config:system:set has_internet_connection --type=bool --value="false"
3.Start a videoconference with the talk app

Expected behavior

video conferencing and screen sharing can be done successfully

The above posted config was missing “has_internet_connection:false”.
This is because I removed the setting after confirming the problem.
