MqttNet - MQTT Client cannot receive all the messages that were published by an MQTT Server

Asked 2022-Mar-27 at 23:38

I publish 1000 messages from an MQTT Server when a client subscribes to a topic. Some of the messages are not received by the MQTT Client. Is this a bug or am I implementing something wrong?

Here are the server and client configuration examples.

As per the comments the issue was with the configuration of the MqttNet Broker.

The setting MaxPendingMessagesPerClient defaults to 250 meaning that when there are 250 messages awaiting delivery for a specific client, and another message arrives, the first message in the queue will be dropped.

Your application is sending messages faster than the receiver can process them so the queue builds quickly and messages are lost. The last 250 messages arrive without issue because nothing new is being sent (so the broker has no need to drop further messages).

To fix this you can use WithMaxPendingMessagesPerClient e.g.

C# is not a language I've done much with, but I assume you are missing an await before mqttClient.ConnectAsync(options, CancellationToken.None); so the rest of the code waits for the connection to complete before trying to send the message

MQTTnet : Unable to connect With TLS : Interop+AppleCrypto+SslException: bad protocol version

Asked 2020-Oct-05 at 15:06

I am a new .NET core user trying to learn how to connect a managed client with TLS on MacOS Catalina, using MQTTnet.

I am trying to connect from ASP.NET Core 3 Background Service to a Mosquitto broker. Using MqttExplorer I am able to connect successfully to the server over TLS, with username, password and a server certificate (CA) file. So, I know the Mosquitto Broker is configured correctly.

However, I am unable to achieve this with MQTTnet.

Is it possible to enable specific Elliptic Curve Cryptography (ECC) cipher suites on the Hololens 1?

Asked 2020-Sep-15 at 03:34

I am trying to start a secure MQTT connection using MQTTNet on the Hololens 1. I managed to load all necessary certificates, however, the connection fails because the EC-Curve sepc521r1 is required. On a Win10 desktop system, this can be enabled using the Powershell command Enable-TlsEccCurve "NistP521".

Can I somehow enable this curve on the Hololens?

I talked to the team a bit further and it doesn’t appear we have a CSP that would enable this. Could you submit a feature request via feedback hub on new feature request to be considered in future releases of HoloLens OS and devices? If it’s a hot impacted feature, it will be possible to be given priority to jump in the development schedule.

For how to post feedback request, you can follow this doc: Send feedback to Microsoft with the Feedback Hub app.
