Subject Re: Found 2 bugs in ACS 4.10. Possibly exist in 4.11 (master)
Date Sat, 06 Jan 2018 06:37:55 GMT
Additional info. In CPVM logs (after SSH to it) I found:

2018-01-06 06:34:03,631 ERROR [consoleproxy.vnc.VncServerPacketReceiver]
(Thread-13:null) Unexpected exception:

It seems, that after this exception it stops function.
