[ary190]

Dear All ,
I have a Sentora Installation , which is working great !
I waned to enable SSL on a domain (example.com) that I host on the system (sentora installation)
I followed the Instruction here:  http://docs.sentora.org/?node=64 
I purchased my Certificate for my domain from Godaddy
I am running my production server on Ubuntu 14

now when I follow the above instruction , the domain gives an SSL error .

Note: I tried the this SSL on a TEST server , and somehow , it worked !!!!

now I don't know whey this SSL not working on my production server !!

please help me to troubleshoot this .

Thanks alot
