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

While submitting post request for Apple Pay Session in Sandbox enviornment, we are getting "The request was aborted: Could not create SSL/TLS secure channel" .

The site is deployed in IIS and has TLS1.2 enabled , with Application using .NET 4.8 framework. All the setup required for Apple Pay as mentioned in the apple pay site are verified e.g. Ciphers, TLS , IPs whitesliting etc and they look good.

We are able to connect thro Postman and same code works when tested from a sample console application in the server hosting the applicaiton

However issue happens only when the session is initiated from the Application.

Any pointers to the above is appreciated.....
