Client disconnects due to "connection reset by peer mqtt" exception

[DaniPazLor]

Hello everyone,
I have made a connection between MqttRabbit and a client computer configured with MqttNet. Messages are processed between the two through the MqttRabbit exchange.
Until now it had worked without problem with messages of less than 1Mb, but when I wanted to increase this message to more than 1Mb it started to fail. If I send 10 messages almost half of them fail in the processing causing the disconnection of my mqttNet client showing the following exception:

From here on, it no longer manages to reconnect, giving the same error every time it tries to reconnect. In turn, mqqtRabbit attempts to resend the message that has failed and is queued several times.
My managed client setup is as follows:

I have done these same tests with a mosquitto client and the result has been satisfactory, so I think that there is something that I have not configured correctly in my mqttnet client that has stopped working correctly when
If anyone has made this same connection between mqttNet and MqttRabbit I would appreciate any help you can give me.
