Unfortunately I get these warning messages again with git revision 8f89ac0.

Prior to that the user wasn't able to use the chat and pion/ice logged
this several times but without further info:

ice WARNING: 2021/02/10 18:59:02 pingAllCandidates called with no
candidate pairs. Connection is not possible yet.

The user left the session and re-entered. This resulted in the user
being listed twice and ~70 messages/sec saying:

failed to send packet: write udp 10.1.1.13:52736->10.1.1.28:49213: use
of closed network connection

Note that this seems to be a connection relayed via TURN server. I can't
tell why relaying was enforced though.

Ciao, Michael.
