AgileDotNet obfuscator messes up httpClient.PostAsync

Question

I noticed that an app obfuscated with AgileDotNet is unable to send httpClient.PostAsync requsts. I trimmed the problem down to 20 lines of code so everyone can try it.

  internal class Program
  {
    public static void Main(string[] args){
      Send("lala", "https://url");
      Console.ReadLine();
    }

    public static async Task<string> Send(string jsonString, string url){

      using (var client = new HttpClient()){

        StringContent stringContent = new StringContent(jsonString, Encoding.UTF8, "application/json");
        var result = await client.PostAsync(url, stringContent);

        Console.WriteLine(result.StatusCode);
        if (result.StatusCode == HttpStatusCode.OK){
          string response = await result.Content.ReadAsStringAsync();
          Console.WriteLine(response);
          return response;

        }else{
          string response = await result.Content.ReadAsStringAsync();
          Console.WriteLine(response);
          return response;
        }
      }

    }
  }

The code below will send a Post request if it is not obfucated. If AgileDotNet is used, it will never send a request. Moreover, error is completely silent as is is not shown in Event Viever nor in the console.

Has anyone experienced this? Any known workarounds? I am using AgileDotNet 6.6.0.11

Update: when changing Main's return type to async Task and calling await Send I recieved an error:

Unhandled Exception: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.

Apparently, establishing SSL connection causes problems.
