Oh my goodness; so silly! After each restart of the machine, each time I did launch all the services: mysql (it autostarts), docker, kurento, tomcat..... except the coturn! I had just completely forgotten about the need to launch coturn.
You are right, Maxim! Coturn was not started. I followed your suggestion, killed the extra tomcats and launched coturn. Everyrhing works superbly now! My international meeting failed yesterday due to this simple oversight on my part. No worries, I will schedule a new one. And thank you for showing me a more efficient way of doing the 'ps' command by piping it to grep to see only the processes I am interested in. Have a good afternoon.
