ADSelfService_Enroll.hta -message appears "Server unreachable , Right Now! ???

I wanted to update the ADSelfService_Enroll.hta file I have in group policy with the latest version (from the last patch I put on 11/20/2015)- I double clicked it to test it to see what my users will see and that message appears. The group policy version (7/20/2015) doesn't give any message - I'm not even sure it's working anymore.
Any help?

thank you,
