This is surely a mismatch between artifact versions. How did you exactly deploy OpenVidu? Did you follow official instructions? Intro - OpenVidu Docs

Hallo, I installed OpenVidu following the instructions On premises - OpenVidu Docs, before I had an older installation of OpenVidu in totally different path, maybe there is some conflict beetween the two versions? i can’t think of a way to them to “interact”, the older one is turned off and lives in another path…
Can you suggest me some way to debug more or to were to look to solve the problem?

Two versions running can not live together and OpenVidu must be always installed at /opt/openvidu to work properly. This also help us to support you and put in the forum answers which are valid for everyone because of the same path being used.

So, in summary, OpenVidu should be installed at /opt/openvidu and the other version should be off and located in another folder.

What is the other version you was using?

yes, my new setup is installed in /opt/openvidu, i followed closely the documentation, and the older version is totally turned off, it’s still on the filesystem but in a totally different path under /home.
The older version was installed on the system without docker, inside /home/xxx, and it was version 2.8.0

Ok, solved, it was my mistake, i turned off everything except the old kurento-media-server.
Now the dashboard of the new installation is working right.
