Hi Hamza , 
Try to disable ASM policy first from your Virtual server and see if this fixed this issue or not ,

-if yes you should see what makes ASM to block opening or downloading PDF files requests ,

-If not you should disable http profile from your virtual server and change virtual server type from standard to performance layer 4 " If this available with you and this web site does not serve production services now " , if this issue resolved , I recommend to disable http parsing against PDF files as clarified in the below KB :

but first differentiate if this an ASM issue or not. 

I hope this helps you
