Stomp.net from docker : The Connection is already closed!

[fjmalan]

Hi Dave

I'm trying to connect to a SSL ActiveMQ stomp server with .Net core

I can connect to the queue when running the project with MacOS or Windows 10
The problem only happens when i publish the service to a docker container.

Connection / SSL Settings

private ConnectionFactory GetConnectionSettings(string brokerUri)
        {
            return new ConnectionFactory(brokerUri, new StompConnectionSettings
            {
                UserName = _configuration["USER"],
                Password = _configuration["PASSWORD"],
                TransportSettings =
                                                     {
                                                         SslSettings =
                                                         {
                                                             ServerName = _configuration["HOST"],
                                                             ClientCertSubject = "",
                                                             KeyStoreName = "My",
                                                             KeyStoreLocation = "LocalMachine"
                                                         }
                                                     },
                SkipDesinationNameFormatting = false, // Determines whether the destination name formatting should be skipped or not.
                SetHostHeader = true, // Determines whether the host header will be added to messages or not
                HostHeaderOverride = null // Can be used to override the content of the host header
            });
        }

_addressRX = $"ssl://{_configuration["HOST"]}:{_configuration["PORT"]}";
_connectionRX = GetConnectionSettings(_addressRX);
var connection = _connectionRX.CreateConnection();
connection.Start();

I get the exception connection.Start();

Stomp.Net.Stomp.ConnectionClosedException: The connection is already closed! ErrorCode: at Stomp.Net.Stomp.Connection.CheckConnected() at Stomp.Net.Stomp.Connection.Start() at deposita_service.Services.DepositaService.StartAsync(CancellationToken cancellationToken) in /app/Services/DepService.cs:line 203

DockerFile

FROM microsoft/dotnet:2.0-sdk
WORKDIR /app

COPY *.csproj ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out
ENTRYPOINT ["dotnet", "out/dep-service.dll"]`

Hi

Thanks for reporting the problem.
Sadly, I don’t have the possibility to test with a docker container.

The exception gets thrown when the library detects a problem with the connection to the broker.
In such a case the connection will be closed and has to be reestablished.

Do you have the logging enabled? (If not see: https://gist.github.com/DaveSenn/92265c1ba45afe258afb9b13c28c5b93 for how to use the internal logging)
Can you see any helpful information in the log output?

@fjmalan Where you able to find the issue or did you find something in the Logs?
