Hello, It seems I am having the same problems as others regarding audio and video.
Here is the setup (Ubuntu 18) after following Alvaro's instructions: Setup 1: VM on vpsserver worked correctly. While users had the https not safe message when using the IP address for the room, we were able to go through the conference with audio and video. This is a backup solutions for us. Setup 2: VM on our internal network. Access is through a VPN from the outside. While users had the https not safe message when using the IP address for the room, we were able to go through the conference with audio and video. Unfortunately, a lot of jitters and random freeze and booting out of some users occured. I believe this is due to the internal cloud server we used. We will not be using this solution (too difficult for some users to setup their vpn). Setup 3: We have a VM instance on Microsoft azure. While users had the https not safe message when using the IP address for the room, everybody was able to access the room and see his/her own camera and see the microphone working. However, the rest of us were not able to hear audio and video from the others. After spending hours on the mailing list, it boils down to us not using a TURN server. I found this link on the mailing list (see post by René Sholtz): https://markmail.org/message/3dgy62lj3m74mogy#query:+page:1+mid:3dgy62lj3m74mogy+state:results These are the instructions for configuring a TURN server (coturn). Since we are using an IP address, did anyone have success in making those configuration steps. Maybe Alvaro has written a setup manual for this part? Thanks
