getting this when running on a server

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

iis8 on windows 2012 R2 (schedule to be upgrade but not yet) .net framework 4.8

 

Working fine with same code on windows 11 pro development pc 

 

try to narrow down what to try next

 

able to get the OpenAPI Specification on the server without issue

Is TLS 1.2 enabled on this server?  Most modern SSL sites require at least TLS 1.2.
