It is a VPS server, and im accessing without any proxy
okay, do you think its application issue or issue due to any missing packages ?

Im using chrome. 

Also checked in Firefox same thing happens.

ok, noticed one more thing, when i stop the service i get the menu panels on the frontend with a black overlay saying connection lost and the 2 gears. 
yes, i can stop the service and start too.. 

is it something related to port ? but i can access the port and log in to panel. 

But after logging it only shows me 2 gears loading.

Any solution for this ?
