connection error 1007 in docker setup

[Bjoern Franke]

Hi,

since several days we get a connection error 1007 in our instance using
the docker setup. Thats some kind of strange as the containers have not
been restarted before. The external IPs in freeswitch's vars.xml are
still correct. Any ideas where to look? While investigating the traffic
from one of the clients to the bbb server, I saw several connection
attempts on Port 19100 UDP - no clue what this is used for. Allowed
ports in the firewall in front of the server are 80/443 and 3478/5349.

Some more questions occur from this issue: in which container do I find
bbb-conf to check the config? And what's the correct way of upgrading?
scripts/upgrade or scripts/uprade-and-build?

Regards
Bjoern

Further investigation turned out we were missing the UDP ports from
https://docs.bigbluebutton.org/administration/firewall-configuration/

It works now again, but somehow it must have been working before with
the turnserver only.
