I am not able to create a merchant session successfully. I am running the .NET framework 4.8. Also, while calling the validation URL with HTTP Client, I am setting the TLS to 1.2 explicitly.
I am able to load the certificate properly, but when calling the URL, it gives an exception "An error occurred while sending the request. "
Inner Exception:
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host
The underlying connection was closed: An unexpected error occurred on a send.
Can you please help? Thank you.
