Microphone and camera inactive after permission

I have the jitsi meet installed in an Ubuntu LXC container, placing the IP of the service in a browser opens the jitsi normally. But when entering a room I configure the microphone and the camera, I give them permission to use them and when clicking on the icons to activate them they remain in a locked state, that is, the microphone remains in MUTE and the camera does not give video on the screen even though it detects the camera in the settings. Please your prompt help.

The domain name given in the installation and the address in the web browser must be the same.

Thank you very much!. I solve the problem.

As indicated by you, you suddenly know how it can be modified in Jitsi-meet so that instead of the domain name I take the ip address of the computer where the local service is installed.
