I’m trying to make some requests using httpclient in C # .Net 4.7 (from windows 10) in a rest webservice that uses Let’s Encrypt Certtificate V3…
Serial number is 03696f6946977cd63d57cae0325468924d8d.
My problem is Let’s Encrypt is a real certificate? because when I make the request, it always returns an SSL / TLS error and the ServerCertificateValidationCallback is not invoked.
ServicePointManager.ServerCertificateValidationCallback = (sender, cert, chain, sslPolicyErrors) =>
what happens?? what am I doing wrong?
anybody can show C# code example???
