Mobil Application Does not Connect to Internet

Hi;

I haveClearOS Lite Edition. Ans 50Mbits 2 WAN and 1 LAN connection on my network. Servers use one IP to reach internet and other computer and mobil devices use other IP to balance of my ınternet. My question is soma application including apple Store does not connect. I have disabled Content filtering and Application filtering but nothing changed.
I do not know how to check ot watch What is the problem or what does not allow this applications? I am not experienced about ClearOS?
I am not sure This problem is related to each other but at the same time ClearOS interface is very slow. sometime I click some links on ClearOS daskboard (ay link) but The link opens more than 20-30 seconds after.
