Hello,

can you advice where we can look for reason of error when trying to reach Console on LXC Containers ( For VM this works OK ).

Connection failed (Error 500: Timeout while waiting for port '5900' to get ready!)

Hi,

so in journal i found

Sep 07 08:14:35 hutivu pvedaemon[19722]: starting lxc termproxy UPID:hutivu:00004D0A:0C177252:5D734ACB:vncproxy:108:root@pam:

when trying to open console, 5900 appear in localhost

root@hutivu:/home/psobota# for i in {3600..1}; do netstat -plnt|grep 590 && sleep 1; done
tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN 23244/perl

tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN 23244/perl

when i start console, but from browser this ending in error like timeout 500, sometimes... console start when i choose xterm.js, but 1 for 10 tries, and problem for now in test lab exist only for CT, mostly we recognize it after upgrading to 6.x some time ago.

Best Regards,
