Can't connect to X11 window server using 'localhost:12.0' as the value of the DISPLAY variable.

We are about to upgrade the 2 Node RAC running on the Oracle 11.2.0.3 in the HP - Unix environment to the Oracle RAC 12.2.0.1. 

When we try to invoke the ./gridSetup.sh we get the error below; 

oracle@ssrncwd1:/home/oracle/.ssh $ cd /app/grid/product/12.2.0.1/ 
oracle@ssrncwd1:/app/grid/product/12.2.0.1 $ ./gridSetup.sh 

Can't connect to X11 window server using 'localhost:12.0' as the value of the DISPLAY variable. 
oracle@ssrncwd1:/app/grid/product/12.2.0.1 $ 

XWindows Application like XMING. EXCEED, Mobexaterm all are tried;  successfully able to launch XClock and Xterm.

Please shed light on this issue.

Thanks

I would
- confirm that the value of DISPLAY is the same in both the failing case (as reported in the error) and the successful cases (as reported by the shell)
- if the value is different, check whether the value is being set by the script; if so, how it arrives at this value (is it trying to launch something like xvnc prior to this)?
