NAV 16 connection with mobile application

Hi to all

For some time, I'm trying to connect to NAV 16 server using Microsoft NAV Mobile application, but all I've got is the message "Could not connect to the server".

1. I've create Self Signed Certificate company.mycompany.com
2. I've installed this certificate on iPad Mini 2 and on mu windows mobile phone.
If i try to connect to NAV 16 using my server's IP address example: https://40.50.60.70/DynamicsNAV90/WebClient/tablet.aspx it's working from browsers of every device. But if I write this link https://40.50.60.70/DynamicsNAV90 on the NAV Application I'm getting error: "Could not connect to the server".

Does any of you guys have experience whit this problem.

Any suggestions is appreciated. Thank you for your time


Best Regards
