Opening a VM console I always get connection closed (error 1006):

There was an error connecting to the VM. This could be due to an invalid or untrusted certificate chain or the VM being powered off. Please use the latest version of Chrome, Firefox or Internet Explorer if the problem persists.

When we used to get this error we determined that although this occurred with PRISM Element (the CVM) when we launched the console from a PRISM Central (a VM), it worked.

Do you have a PRISM Central?

Good luck!

In prism central I see a GREY console that says: noVNC ready: native WebSockets, canvas rendering

Have you tried KB-5855 as suggested by Nashma earlier? What was the outcome?

It works: adding the correct DNS server to prism as suggested in
