--- Comment #1 from [e-mail] ---
This problem does not occur on Ubuntu 21.10 using wine-7.0 (stable)

It occurs on Fedora 34 using both wine-7.0 (stable) and wine-7.2 (staging)

An exception is thrown when executing the following code:

string baseUrl = "https://update.crysiswarsmp.com/";
using (System.Net.WebClient client = new System.Net.WebClient())
{
    client.DownloadFile(baseUrl + "/launcher.txt", "launcher.txt.new");
}

ex.Message:
  Error: TrustFailure (Authentication failed, see inner exception.)

ex.InnerException:
  System.Security.Authentication.AuthenticationException: Authentication
failed, see inner exception. ---> Mono.Btls.MonoBtlsException: Ssl
