Code works differently in Docker container

I have ported a consoleApp to a Docker container with the mcr.microsoft.com/dotnet/sdk:6.0. Now I noticed that the code inside the container behaves differently. Outside the container, an exception is generated when the connection is lost but Not inside the container! What can be the reason?
Many thanks for your help.
public static async Task FtpUploadAsync(string hostname, string username, string password, string[] uploadfiles)
{
try
{
var token = new CancellationToken();
using (AsyncFtpClient client = new AsyncFtpClient())
{
client.Host = hostname;
client.Port = 21;
client.Credentials.UserName = username;
client.Credentials.Password = password;
client.Config.EncryptionMode = FtpEncryptionMode.None;
client.Config.InternetProtocolVersions = FtpIpVersion.IPv4;
client.Config.ValidateAnyCertificate = true;
client.Config.ConnectTimeout = 15000;
await client.AutoConnect(token);
Console.WriteLine("Connectetd!");
foreach (var varFilePath in uploadfiles)
{
Console.WriteLine("Uploading File: " + varFilePath.GetFtpFileName());
await client.UploadFile(varFilePath, "/" + varFilePath.GetFtpFileName(), FtpRemoteExists.Overwrite, true, token: token);
File.Delete(varFilePath);
WriteLogFile.WriteLog("File Uploaded", varFilePath.GetFtpFileName());
}
}
}
catch (Exception ex)
{
WriteLogFile.WriteLog("catch", "Ftp-Uploader " + ex);
Console.WriteLine("Ftp-Uploader " + ex);
}
}
Hello, how do I include the code to write a debug log! Unfortunately I can't get it! Sorry....
using FluentFTP; // from NuGet package FluentFTP
using FluentFTP.Logging; // from NuGet package FluentFTP.Logging
var builder = WebApplication.CreateBuilder(args);
var logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.File("logs/Net6Tester.txt", rollingInterval:
RollingInterval.Day)
.CreateLogger();
client.Logger = new FtpLogAdapter(logger);
here are the logs! when i run the coed on a windows system then it disposes after a disconnection.
If I run it in the container, then it immediately wants to continue with the next file in the array!!

To configure logging from FTP client you can use the following:
According to FluentFTP Logging page you can setup logging via Serilog. Add the following NuGet packages:
Serilog
Serilog.Extensions.Logging
Serilog.Sinks.File
(optionally, to log to console also) Serilog.Sinks.Console
On the start of program configure logging:
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Verbose()
.WriteTo.File("logs/Net6Tester.txt", rollingInterval: RollingInterval.Day,
outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")
.WriteTo.Console(outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Message:lj}{NewLine}{Exception}")
.CreateLogger();
Then when you create AsyncFtpClient configure it to log to Serilog:
using (AsyncFtpClient client = new AsyncFtpClient())
{
var logger = LoggerFactory.Create(builder => builder.AddSerilog())
.CreateLogger<UploadClient>();
client.Logger = new FtpLogAdapter(logger);
You can also log yourself with something like this:
Log.Logger.Information("Uploading file {0}", varFilePath.GetFtpFileName());
Please first make sure it's logging as expected on your host machine. Then try to get the logs from Docker container.

How can I download a file with Hebrew characters in its name from an ftp server via .net console application?

I am using a .net console application written in C# to download certain files from an ftp server routinely, it used to work properly until there was a file with Hebrew characters, named something like that:
1234--אבג.jpeg
so I've tried to download the same file using both chrome and FileZilla - and encountered no problems, with neither plain nor URL encoded version of the filename.
My problem is how to download the same file with my C# application
I have tried:
to escape the name as URL-encoded, worked for chrome but not my APP
to convert the string to utf-8
both System.Net.WebRequest and HttpClient
finding and taking the name from response of directory listing and pasting into the request, hoping it will have the proper format.
here is my code :
public static string attachmentToFile(string name, string filename)
{
try
{
string ftpConnection = ConfigurationManager.AppSettings["FtpServer"].ToString();
string ftpUser = ConfigurationManager.AppSettings["FtpUser"].ToString();
string ftpPassword = ConfigurationManager.AppSettings["FtpPassword"].ToString();
string attachmentPath = ConfigurationManager.AppSettings["attachmentFolder"].ToString();
Directory.CreateDirectory(attachmentPath);
attachmentPath += '\\' + name + Path.GetExtension(filename);
FtpWebRequest attachmentRequest = (FtpWebRequest)WebRequest.Create(
new Uri(ftpConnection + "/files_directory/" + filename)
);
attachmentRequest.Credentials = new NetworkCredential(ftpUser, ftpPassword);
attachmentRequest.Method = WebRequestMethods.Ftp.DownloadFile;
FtpWebResponse response = (FtpWebResponse)attachmentRequest.GetResponse();
var stream = response.GetResponseStream();
FileStream saveStream = new FileStream(attachmentPath, FileMode.OpenOrCreate);
//stream.Seek(0, SeekOrigin.Begin);
stream.CopyTo(saveStream);
saveStream.Close();
return attachmentPath;
}
catch (Exception ex)
{
Logger.LogError(MethodBase.GetCurrentMethod(), ex, "failed downloading file from server: " + filename);
return null;
}
}
the error is
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

although I didn't find the exact reason for the error, after printing FileZilla verbose log and FtpWebRequest as suggested in the comments and reading some more I have read that it's hard to change certain configurations using System.Net.WebRequest and HttpClient, so I used a 3d party library (FluentFTP) there were many configurations available but I didn't need to do anything in my case and the problem was solved by the default configurations.

FTP Upload from WinService fails

I have made a small test application(WinForms C#) to test FTP upload. This works perfectly.
I try to use the exact same method in a Windows Service I'm currently working on, but there I get '(426) Connection closed; transfer aborted.'-message.
I have made sure several times that the parameters to the method are exactly the same. They are! Next thought was the account my service is running under, but I've tried all possibilities, even running the service as 'User', supplying my own credentials. Then it should act like the WinForms app, right? No, it doesn't!
It's running fine until the line using (var requestStream = request.GetRequestStream()) which is the point of failure.
The FTP-server in question only allows active connections, so request.UsePassive is set to false.
Anyone got a clue?
public void UploadToFtp(string url, string filePath, string username, string password, bool mode)
{
var fileName = Path.GetFileName(filePath);
var request = (FtpWebRequest)WebRequest.Create(url + fileName);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(username, password);
request.UsePassive = !mode;
request.UseBinary = true;
request.KeepAlive = false;
using (var fileStream = File.OpenRead(filePath))
{
using (var requestStream = request.GetRequestStream())
{
fileStream.CopyTo(requestStream);
requestStream.Close();
}
}
var response = (FtpWebResponse)request.GetResponse();
response.Close();
}

The one that works has a line saying 'RAS Supported'. Maybe interesting, don't know.

The Windows Firewall caused the problem. When running from a WinService I had to open the firewall for this service. When running from VS environment it seems that the firewall is already open for VS (although the list of pass-through applications in WinFirewall don't show it) and therefore all seems to run well.

Fetching AccessToken returns "400 - Bad Request" for authenticating cloud service with WNS [duplicate]

PLEASE HELP!! Can't figure out why this simple code given by MSDN doesn't work....
I am using the following code in GetAccessToken() as given in the this MSDN article to get the access token to be used in windows notifications, but it returns "Bad Request 400"
PACKAGE_SECURITY_IDENTIFIER, CLIENT_SECRET are the values obtained when the app was registered with the Windows Store Dashboard
string urlEncodedSid = HttpUtility.UrlEncode(PACKAGE_SECURITY_IDENTIFIER);
string urlEncodedSecret = HttpUtility.UrlEncode(CLIENT_SECRET);
string body = String.Format("grant_type=client_credentials&client_id={0}&client_secret={1}&scope=notify.windows.com", urlEncodedSid, urlEncodedSecret);
string response;
using (WebClient client = new WebClient())
{
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
response = client.UploadString("https://login.live.com/accesstoken.srf", body);
}
Any help would be highly appreciated.......

I suspect the problem has to do with either an incorrect package identifier, and / or incorrect client secret.
From the MSDN page Push notification service request and response headers:
RESPONSE DESCRIPTION
--------------- --------------------------
200 OK The request was successful.
400 Bad Request The authentication failed.
Update - I ran the code from the question, using FAKE credentials.
Here is the RAW HTTP request:
POST https://login.live.com/accesstoken.srf HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: login.live.com
Content-Length: 88
Expect: 100-continue
Connection: Keep-Alive
grant_type=client_credentials&client_id=test&client_secret=test&scope=notify.windows.com
Here is the server's RAW response:
HTTP/1.1 400 Bad Request
Cache-Control: no-store
Content-Length: 66
Content-Type: application/json
Server: Microsoft-IIS/7.5
X-WLID-Error: 0x80045A78
PPServer: PPV: 30 H: BAYIDSLGN2A055 V: 0
Date: Thu, 21 Mar 2013 12:34:19 GMT
Connection: close
{"error":"invalid_client","error_description":"Invalid client id"}
You will note that the response is a 400. There is also some json that indicates the type of error. In my case, the error is Invalid client id. You probably want to take a look at your response - it will give you an indication of what happened.
I used Fiddler to debug the request/ response.

I found the reason for the error response. In fact it is the wrong PACKAGE_SECURITY_IDENTIFIER and CLIENT_SECRET.
DO NOT type the values. Because associated ASCII values differ. Therefore it is always better to copy and paste directly.
You will probably will get the access token with the simple code snippet.
Cheers

If you're using the new HttpClient API and you're sure you've copied and pasted the SID/secret values correct, you might be experiencing this issue because of encoding, provided you're using the FormUrlEncodedContent class as the content of your POST operation.
Contrary to the examples in the MSDN documentation, you don't want to URL encode the SID and secret values before adding them to the KeyValuePair collection. This is because encoding is implied by the FormUrlEncodedContent class, though I'm not seeing any documentation for this behavior. Hopefully this saves someone some time because I've been wrestling with this all night...

This is a log of my requests and responses. I have a separate thread listening on port 58830 accepting udp packets (Tested sending udp from another computer and were received).
Wireshark shows the requests and response but no udp packets. I looked at the back and forth between server and vlc and my request are almost identical but I still receive no udp video data

Your SDP File's IN ADDR seems invalid 0.0.0.0...
Some stacks use the information in the SDP and this could explain why you are not receiving any packets on the address your are listening on.
Also it looks like you are doing multicast, have you ensured you setup the socket correctly before hand?
