I have an API that takes in XML and ultimately uploads files based on information in the XML. The uploads are on a schedule (also from XML), and I have tested everything surrounding it and know it works.

I am getting an error about 40% of the time on the first file that I attempt to upload in each time cycle (time cycle = 45 minutes for some files, 30 minutes for others).

Here is my code for the upload:

try {
    LoggerFTP.Log("Uploading file: " + filename, false);

    // Create the request.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(appSettingsFTP.ftpUrl + @"/" + filename);
    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.Timeout = 6000000; //set to 100 minutes
    //request.Timeout = -1; //set to infinite

    // Add the login credentials.
    request.Credentials = new NetworkCredential(appSettingsFTP.ftpLogin, appSettingsFTP.ftpPassword);

    // Grab the file contents.
    StreamReader sourceStream = new StreamReader(appSettingsFTP.uploadFileDirectory + filename);
    byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
    sourceStream.Close();
    request.ContentLength = fileContents.Length;

    // Copy the file contents to the outgoing stream.
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(fileContents, 0, fileContents.Length);
    requestStream.Close();

    FtpWebResponse response = (FtpWebResponse)request.GetResponse();
    //Logger.Log(filename.ToString() + " " + "Upload Complete, Status: " + response.StatusCode + " " + response.StatusDescription, false);
    //Took response.StatusDescription out because it appears to be creating extra line feeds.
    LoggerFTP.Log(filename.ToString() + " " + "Upload Complete, Status: " + response.StatusCode, false);
}
catch (Exception ex) {
    LoggerFTP.Log(ex.ToString(), false);
}

I have researched the issue and saw something online about it potentially being a speed thing. Lik
