I seem to have a noVNC-related issue. From time-to-time, I get a "Server disconnected" error, when accessing my VM's through VNC. I've noticed that it usually (only) happens when I was previously connected to that specific VM (for which the error occurs) through VNC for an extended period of time (but not more than 10-15 minutes), closed the connection, and then tried to reconnect (this is where I get the error). It never happened (so far) in situations other than this, if the VNC-connections are short-termed in time, I can close and reconnect to VM's through VNC as many times as I want.

The only workaround I've found so far is rebooting both the front-end and the respective host, which, as you can imagine, is rather inconvenient to do each time this error occurs.

sunstone.log contains the following about the

Starting vnc proxy: /usr/share/one/noVNC/utils/wsproxy.py 35822 pcls:5946

Since I'm not an expert in Python, I didn't want to dig myself into the above-named files so far.

Any ideas what should I check, or what should I do?

Thank you,
