We unforked our jitsi web container and discovered that etherpad doc
embedding was broken. In the process of debugging this the jitsi meet
services on meetpad were restart which pulled in newer configs which
expect ENABLE_XMPP_WEBSOCKET to be enabled by default. Unfortunately
this wasn't quite working for us. Explicitly disabling this seems to
make audio and video calling work again. But doc sharing isn't even
attempted now.
Let's get this fix in as audio and video are important then we'll keep
debugging the etherpad doc sharing problem.
https://github.com/jitsi/docker-jitsi-meet/issues/902 has details from
others that hit this problem.
Note that part of the issue here seems to be that nginx is using the
default configs in the container found at /default and not the configs
we bind mount at /config. This at least seems to be why the proxying for
etherpad documents is broken.
