I will go to 3.4 then. > Hi Amos I built a new proxy, stock standard settings, and tested it again. With IE11 and SPDY/3 enabled I still get the initial "page can not be loaded" problem. When doing a refresh immediately afterward, it loads the page. On the plus side, Sharepoint sites now work. :-) Any suggestions? Kind Regards Jasper
