Hi there!
 try this:
To show existing password:
$ sudo cat /Library/Preferences/com.apple.VNCSettings.txt
7F513D02E4A8C5E2FF1C39567390ADCA
$ sudo cat /Library/Preferences/com.apple.VNCSettings.txt | perl -wne 'BEGIN { @k = unpack "C*", pack "H*", "1734516E8BA8C5E2FF1C39567390ADCA"}; chomp; @p = unpack "C*", pack "H*", $_; foreach (@k) { printf "%c", $_ ^ (shift @p || 0) }; print "\n"'
hello

if you have changed the password recently you may try to restart the service. Are you sure you are connecting to the right VNC server (screen)? I have feeling this is some sort of user error here.

Hi!
you need to replace pws_admin with your pws_admin username I believe.
