Hello Maxim, we use OM 5.1.0 since March or April this year. Bevor we used (and still use it at the moment) OM 4.0 on a windows server. The change is necessary because of EOL of FlashPlayer. We saw that OM 5 don’t need FlashPlayer any more so we decided to change to this version. Our environment runs entirely on vmware. We use thinclients and Windows Terminalserver without connection to the internet. For my first test of the new version I installed on my private Laptop Debian in a VirtualBox. Here I used your guide, but OM doesn’t work and I got always the message “connection to KMS failed” or similar. I saw that the KMS is running under Debian in Docker and under Ubuntu 18.04 in a local installation. I thought it’s maybe a problem with docker so I decided to try it with Ubuntu 18.04, using your guide and everything worked fine. After some successful tests at my private Laptop we decided to use it so I’ll will install a new and fresh maschine. At this installation I found out that 6.1 was released so I installed it. Everything looks good and I transferred this image in our environment. Here we got a problem. When I try to send out an invitation to a meeting no form appeared. Only the monitor was grayed out and nothing happens. We have determined this behavior with all forms when we use virtual maschines like our Terminalserver. When I use a physical Maschine everything works fine. In OM 5.1.0 this could not be determined, so I decided to use 5.1.0 at Ubuntu 18.04. If necessary we will try to update the KMS. For to do it we use here Nexus and we must insert the Repositories there. For Ubuntu the repositories are already inserted there. I think for to update the KMS we must insert the Repositories at the Nexus. Can we use these two Links: deb [arch=amd64] http://mirror.yandex.ru/ubuntu/ bionic main restricted deb [arch=amd64] http://mirror.yandex.ru/ubuntu/ bionic universe which are listed in the installation instructions? Can we do the same to install the TURN?

TURN might be required in LAN due to WebRTC is peer-to-peer so not only client should be able to connect the server but the server should be able to connect the clients ...
