    Estou com o mesmo problema, ao realizar uma comunicação MTLs ele informa que

     

    { Error = True, Data = System.AggregateException: One or more errors occurred. (The SSL connection could not be established, see inner exception.)
    ---> System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
    ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.
    ---> System.ComponentModel.Win32Exception (0x80090326): Mensagem recebida inesperada ou formatada incorretamente.
