Hi Peter. No, it doesn't work at all. I ended up downgrading the android app version to 1.1.5 which doesn't require certificates and it worked fine.
As far as I could understand, the issue is related to the fact that I'm resolving the IP via the hosts file in the android device (thats because I don't have a public address available nor an internal DNS at the server). The login process works fine but internally the app cannot retrieve menus and data.
I will ask the server admin to set up a public domain and then I'll try again with 1.2.2 version. In the meantime 1.1.5 version is pretty fine.
Thanks!
