Not able to run 'xclock' command using MobaXterm

Issue: Not able to run 'xclock' command using MobaXterm.

Error:
$ xclock
MobaXterm X11 proxy: Authorisation not recognised
Error: Can't open display: localhost:10.0

Solution:
Step1: open MobaXterm->Setting->X11->set 'X11 remote access' to full
Step2: export DISPLAY=<IP-Address>:0.0
example: export DISPLAY=127.0.0.1:0.0

now xclock should work without issues.
