Web page not displayed

Hello,

 

We had a web service(http) which users were accessing directly. It has now been decided to be accessed via a service on F5. VS & pools are created. when users test access, the web page doesn't seem to load. It gives no error, but just a blank screen.

 

Is there any troubleshooting that can be done from F5 side of things? Please help.

 

Thank you.
