File transfers through F5 LTM failing

Thanks for the response, the app admin has informed me that the web version works without issue. I orginally thought that the server needed to know it was HTTPS on the other end (ie client) so I had the F5 to do SSL to the backend server (have to terminate the SSL to route on the URI) . Since switching off SSL on the backend I know get:

 

 

WebExceptionMessage: The underlying connection was closed: The connection was closed unexpectedly.

 

 

Have to admit confused as it appears the client uses POST requests to download the file (per the bottom text)

 

 

I've managed to do a packet capture on the server side (now its talking plain HTTP) ,however I'm a little stuck on the client side as its a thick client without trying to get a MITM proxy up and running (having a bit of prob turning the cert in to a jar keystore for some reason).

 

 

Real long shot - is there anyway to perform a packet capture on the F5 of the packets its sending to the client prior to it being SSL wrapped?
