Trying to get my iPhone and another employees iPhone setup with the NAV App and on both devices we are running into the, "Could not connect to the server" Right now we are just using our internal wifi network and if i take the same URL that's supposed to go into the "service name" and put it in a browser on the phone it works flawlessly, So i know i have the correct URL unless theirs something special im missing.

The same app and server info works fine on android..

iPhone 6s on iOS 9.0.2

Our Nav is 2016

The instruction to use the settings to enable the trust of the certificate on the iPhone worked perfectly. Thanks.

You have to enable the settings under Settings > General > About > Certificate Trust Settings. Under "Enable full trust for root certificates," turn on trust for the certificate. Then only u can run the Dynamics Nav app from Iphone.

On my iPhone I had to go into Settings, General, Certificate Trust Settings, ENABLE FULL TRUST FOR ROOT CERTIFICATES for my self signed certificate. Only then would I get prompted to login instead of "Could not connect to the server".

As other members suggested, you need to check if you made needed trusted certificate installation.

Are you using the same certificate that works on android in iPhone.

Check if you have multiple certificate installed on iPhone, if yes remove them.
