cannot use secure map service

[HuyHo]

We have a secure tiled map service that we wish to consume in ArcGIS Runtime 10.2.7.  But when we run it, we get the following error:

Layer could not be added to Map because layer initialization failed. See InnerException for more information.

InnerException: The request was aborted: Could not create SSL/TLS secure channel.

I open the same map service using ArcGIS Online, ArcMap, JavaScript, and Quartz Runtime, they all work.  Is there something I am missing?

- OS (Windows 7, 8.1, 10, Phone 8.1...)

- .NET version (4.5.2, 4.6, 4.6.1...

Cheers

There seems to be some issues with the SSL certification or validation of it. See this SO thread with some good tips how to handle it: c# - The request was aborted: Could not create SSL/TLS secure channel - Stack Overflow

Thanks Morten! That appears to be the issue, I got the map to display after following the suggestions on Stack Overflow.
