Authentication error

Hi ~everyone
I have a problem and need help

UltraVNC> :5902> Enter the normal lock screen> However, the password field will always refresh.
I key in a letter or press a key to keep it typing, and it will be cleared immediately. There is an Authentication error message below the field. (Left picture),
If I press ESC, it returns to the initial blank screen (right picture). Move the mouse a little, and it goes here to enter the password but authentication error screen (picture on the right).
If I open vsphere first, after starting VM Remote Console from there, I open the UltraVNC connection again, the password will not refresh. But not every time.

Can anyone help me out, thank you.


  • Are you able to boot the host to Run Level 3 (no GUI) and login at a console? How about SSH?
