Hi,  
my users experince problems using calls.  
Generally it does work, but from time to time the call falls silent.

I know this log output is mentiond in other issues, but none of these apply to my setup.  
No Docker, no Firewall involved.

What else could it be ?

Hi Daniel,

what mattermost server version and calls plugin version is this? Also are only specific users affected by that or specific clients (mobile, desktop) or operating systems?
