You've installed the Microsoft Dynamics CRM phone and tablet app, then receive the following error when you try to connect to your Microsoft Dynamics CRM organization:
Windows / iOS Application:
"Your server is not available or does not support this application"
"This operation failed because you're offline. Reconnect and try again."
This error can occur in an on-premises environment if the certificate for the Microsoft Dynamics CRM website or federation server, such as ADFS, isn't trusted.
This error can occur with an online organization if your organization is federated with Office 365 and the certificate for your federation server, such as ADFS, isn't trusted.
Make sure the SSL (Secure Sockets Layer) certificate used is trusted by using a publicly trusted certificate or add the Certificate Authority certificate for the certificate of the Microsoft Dynamics CRM website and the federation server to the device.
Adding the Certificate Authority certificate to the proper device will require you to export the Certificate Authority certificate from a device that has it and then import it. In most cases, you can get the exported certificate on the device and open it to install/import it.
If you capture tracing, the following error is logged:
"Security certificate required to access this resource is invalid"
"Loading app failed due to SSL error"
For more information about installing the Certificate Authority certificate, see the following articles:
