Unable to download iOS apps after enrollment - Xenmobile

users were unable to download apps from worxstore after enrolling iOS devices. But they are able to download apps on Android devices.

Issue: APNS ports 2195 and 20196 were opened through proxy. As per Apple, these ports should open directly (without proxy) from Xenmobile Device manager server. Please see the article for reference:

It started working after opening APNS ports directly(without proxy) from Device manger.

Verifying ports:
 Login device manager server and open cmd prompt:

telnet gateway.push.apple.com 2195
telnet feedback.push.apple.com 2196

Have a nice Day!!!
