Describe the bug

Is the problem only with the documentation requirement? Or also when calling endpoints?

[Majidgholipour]

Occurs when calling endpoints

[tcsidevtools]

I could be wrong here but I believe this NuGet package doesn't do much when it comes to calling the endpoints. It shows you the documentation and serves the JSON files.

The error you show is a name mismatch. which happens when the self-signed certificate has a common name that does not match the domain name the server is using. The dev certificate which is utilized in asp.net is only assigned localhost as a common name and so any other domain will cause that error.

You should generate a certificate that matches your domain name. and/or use the subject-alternative name on the certificate in the case that you have multiple names the server may go by. I'm unsure if there's another way to do this. But I did do a pull request which allows you to generate a named HTTP client. You can use that to prep an HTTP client with the certificate preloaded for use.
