Hello;

We have SDP 9.0 Build 9004. 

If device is in internal network, SDP Android app can connect to SDP successfully. If the device is outside of the company network, Android app can not connect to the application.

Yes I know, you'll recommend me check firewall and gateway devices but they have been already checked many times. We can connect to SDP web interface with browser by using 80/443 ports from outside of company network successfully. So it proofs that 80/443 ports are open.

Do you have any idea why my Android app can not connect to SDP server?

Thanks&Regards
