Hello Tom,

coturn config looks good
this config has placeholders like
       listening-ip=$Docker-Bridge_Interface-IP$
do you have something like this in the openmeetings.properties as well?

These Placeholders are not in the real config,there are the according
ip-addresses ;-)

I used the placehodlers inside the published config to state clearly
which ip-address is used (coturn is listening as well to external ip and
docker bridge interface at the same time) where and inside
openmeetings.properties i use the ip of the external interface  as
websocket-adress for kms and  the external ip for kms.turn.url,
switching the kms.turn.url also to docker bridge ip leads to only seeing
my own streams so i kept using the external ip actually, but then i got
the mentioned switchingproblems when using a second room running on the
other node at the same time :-/

...(cut done stuff)
All i have to figure out now for my small 2 node cluster is why the switch to 
another room on the other node still results in seeing only my own stream but 
not the opponents (tested with 2 computers here in my lan and 2 others from 
another lan at same time,after switch every computer has only its own streams 
visible+hearable)...

Do you have TURN server?
Is it configured properly?

For sure i have one turnserver per node running ;-)

Heres my turnserver config stripped down to all lines without the commented 
lines and personal information replaced by placeholders which tells the kind of 
content, maybe i have forgoten something in there?

/etc/turnserver.conf :

######################Start#####################

listening-ip=$External-Node-IP$
listening-ip=$Internal-own-IPSEC/GRE-Tunnel-IP$

allowed-peer-ip=$External_other_nodes_IP$

###########################End################

when i put "lt-cred-mech" additionally in there as mentioned somewhere in the 
mailinglist before, my coturn won´t start up and in the logs it tells me to use either 
lt-cred-mech or use stat-auth but not both at the same time...


Hope this helps locating the reasons for my Node-switching problem with the 
streams...


Does anyone on the list have a hint for me if this config has something in 
which may cause the Node-Switchingproblems?

kind regards,

  Tom
