The SSL connection could not be established ..... The function requested is not supported

[pmbaokhanh]

Hi,
I have a .net 6 project using this library. Everytime I call zendesk api using the library I have below error, while same credential using postman works. It appears that authentication failed, but I could not find out where I am doing wrong, could you help please?

Code

var api = new ZendeskApi("xxx90260309", "[email protected]", "xxx");
var me = await api.Users.GetCurrentUserAsync();

Stacktrace
