 Too little information at present to tell.

Does it work if the system is in permissive?

Did you ever have the system in disabled and then switched to
permissive/enforcing?

Do you have xauth installed?

9 times out of 10 with this message it's just that there is no (or
incorrect) .Xauthority so the X server rightfully denies the untrusted
connection.
