C# Can't answer on PING

Chat and IRC

I’m confused why you’re sending a PING message to twitch since those should only ever be received by a client, not sent. However your response message looks like it’s formatted correctly. I would check to make sure that StreamWriter properly appends \r\n since any other combination violates the IRC spec and might be seen as a garbage message. Are you able to successfully send other messages with your SendIrcMessage(...) function?

For reference, this is my writer which works as of last night. (Also in C#)

public void
Pong(string trailing = "")
{
    string message = "PONG";
    if (trailing.IsValid())
    {
        message += " :" + trailing;
    }

    Send(message);
}

public void
Send(string format, params object[] arguments)
{
    ExceptionUtil.ThrowIfInvalid(format, nameof(format));

    string message = !arguments.IsValid() ? format : string.Format(format, arguments);
    if (!CanSend(message))
    {
        return;
    }

    byte[] bytes = Encoding.UTF8.GetBytes(message + "\r\n");            
    stream.Write(bytes, 0, bytes.Length);
    stream.Flush();

    OnDataSent.Raise(this, new DataEventArgs(bytes, message));
}
