[one-users] [Beta 3.0] VNC "Failed to connect to server" problem

[Christoph Raible]

Hi,

after some problems to my Master-Server(no problems from OpenNebula ;) )

I restarted my Master-Server and now noVNC works perfect...

Please don't ask me what has changed after the reboot... I don't know :D
I only want to give you my feedback that it is now working :D

best regards,

Christoph
