jabber update not working

[jtaveras914]

Hi Guys, since i had great luck posting here for my first question, i figure the second should be easy for you.

We use CUCM 10,5.x jabber 11.5.x and up, IIS server on windows 2012r2

I have set up IIS server to host Jabber Pictures of users and its working perfectly when internal. Im trying to host the jabber-update.xml file to point to that server to pickup the update and install but that is failing. Had cisco on the call and they are just giving me the run around for 4 weeks now, do this and that or this and that and do it again..expecting a change.

Manually going to the URL links works and files download fine. On windows when i click update, i get: a problem persist with the software update server. could not conctact the software update server. on a MAC; nothing happens

PS: on a mac a new log on finds the update and finishes, but people that already had been using jabber cant update 

Anyways here are my files and any help is appreciated
