noVNC is not working for VMs with password enabled

See original GitHub issue

Description After upgrade to 5.8.4 I faced with the issue when most of VMs have no working VNC. Usually it is stacks on this screen without any errors:

But after few minutes, it shows:

and error in browser’s console:

    _fail rfb.js:677
    RFB rfb.js:277

To Reproduce

Create VM with

GRAPHICS = [
  LISTEN = "0.0.0.0",
  RANDOM_PASSWD = "YES",
  TYPE = "VNC" ]

Try to connect via VNC

Expected behavior Connected VNC

Hello. I have been testing opennebula 5.8.5 and noticed that apparently this issue was not completely resolved with the fix.

The VNC windows is now available when using a password, but is still not displayed when the option “Open in a new Windows” is then used.

I also tried inserting the fix manually and rebuilding the 5.8.4 packages, with the same result. Hope that this issue was the right place in which to pass this information (reopening the issue?).

hi, @goncaloist, when you click on the “Open in a new Windows” button in the url do these parameters come out? a &encrypt=no&title=TITLEVM&password=PASSWORD

Hello. I was seeing only: “&encrypt=yes&title=TITLEVM”. Now tried adding the &password=… and it worked. I noticed that my “vnc_request_password” option was set to true. Changed it back to false and it now opens the new window. I had misunderstood the purpose of that option. It was no bug, working as intended. Sorry, I had stumbled in this bug with 5.8.4 previously and though my “open in new window” issue was something related.
