Can not run application when using F5 LTM

Hi experts,

I would like to seek your help as we've been having this issue for few weeks already. We have this URL that when we open the url it should actually open file name Symphonyweb.xbap.

If we direct connect to the server there is no issue. Traffic via GTM have also no issue at all, this is by creating the server at node at GTM.

However, using LTM VIP we always end up with an error as shown below. Every time we open the url its just download the symphonyweb.xbap file and nothing happens.

Hope anyone can advise. Thank you very much in advance.
