Android enrollment service not reachable

Hi,

I'm working on a clean Afaria SP4 install (I installed SP3 and immediately upgraded to SP4). I've installed the enrollment server on the same machine and can see it running (AfariaIPhoneServer service).

I've filled up the enrollment server settings in configuration/components and created an Android enrollment policy. When I try using the code on an Android tablet, I get an enrollment failed message. If I inspect the policy, get the long URL and attempt to open it in a browser, I get a connection unavailable error. This is the URL's format:

https://<my IP>/aips/aipService.svc/GetEnrollmentSeedData?ID={400738e7-83e2-4db0-89d2-b2e549524a7a}&ClientType=-10

If it matters, the IP is an internal one and the Afaria server is not reachable from outside our LAN. It is however from the tablet which is connected to our WiFi.

Would anyone have an idea of what could be going wrong?

Thanks

Cédric

PS: bonus question: has anyone successfully used Afaria SP4 for enrollment and OTA app install on Windows Phone 8?
