I did a new installation just to be sure, got the same error, but a restart oft he server fixed it. Thank you for the help.


Now the problem is, that the connection to the media server fails and it starts to reconnect – most of the times this doesn’t work. I’ve tried different browsers (firefox, edge (latest), chrome) and get the same behaviour.


Any idea?

this error has been reported previously

The solution was: restart everything, ensure there is only one KMS and only one OM running

Hi Elisabeth,


what version of Kurento (and OM) are you running?

I’ve installed the openmeetings server now a second time – after screwing up my first, nicely running installation by trying to be too clever.


Now it runs again but I am getting the following error „Failed to start broadcast: Object 'f8ea123c-d0da-40a2-9339-516c027e6b58_kurento.MediaPipeline' not found (Code:40101, Type:null, Data: {"type":"MEDIA_OBJECT_NOT_FOUND"})“ whenever I try to switch on my microphone.


Is it a small mistake or shall I start all over?
