No audio over HTTPS, Cloud Server

[Dongato97]

Hi, I recently installed a NoMachine Cloud Server on an Ubuntu 24, and I added several virtual machines, also running Ubuntu 24, to test the web connection. That is, from a Windows 11 laptop, I access the Cloud via web:4443 and from there to one of the test VMs. Everything is running within Proxmox.

For the various tests I need to run, I need audio. We have audio from the NoMachine Cloud client, both to the cloud and directly to the VMs. However, when I try to connect via web https:4443, I don’t get audio on any machine.

NoMachine Cloud version is : 9.0.188

Hi, did you try with a different browser to see if audio is missing also with a different browser?

We are a aware of a similar problem, reported in web sessions. As a solution for audio in web sessions with server v9, it should be enough to set in server.cfg:

AcceptedWebMethods webrtc

or (if you want a failover in case the browser doesn’t support webrtc):

AcceptedWebMethods webrtc,mjpeg

(Remove the prepending # from the key name, if present).

Then connect a new web session. You can track the fix for this issue using the following link: https://kb.nomachine.com/TR06W11399.
