In case if you stumble upon this question this is what I have observed.
So after struggling for few days I have come to conclusion that there is no easy or straight forward way to resolve this unless I have a second URL where I can expose my log file thru browser. This works well but it does have associated security risk as anyone with the URL can view log contents.
The other solution is to ask your service provider to provide remote access to server this is more secure approach.
