Unable to access Mysites outside server

I have set up Mysites and I am able to access it on the server. But I am unable to access it outside the server. However I am able to access a different site on different web application fine outside the server.

Things I tried -

1) Added an entry to hosts file. 2) AAM added to Default zone. 3) Both web application exists on port 80 4) Tried to ping both host names outside server where Mysites hosts did not resolve

I believe disabling loopback on the server is for the access on the server.

Am I missing anything obvious here? Any help is appreciated
