mqtt protocol not recognized [closed]
Hello there.
I have a connection between a mqtt broker and a client on the standard port 1883. The communication is visible in wireshark. IP,TCP is shown but mqtt is not recognized.

What version of Wireshark are you running? Can you provide Help -> About Wireshark details?
Without knowing anything more, I might suggest that you check the MQTT protocol preferences (Edit -> Preferences -> Protocols -> MQTT) to be sure the MQTT TCP port is set to 1883. You could also check to make sure the MQTT dissector is enabled: Analyze -> Enabled Protocols... -> MQTT.
Hello,
thanks for replying.
The version is 2.6.3, the MQTT Port ist set to 1883 and the dissector is enabled for mqtt.
Ok. I tested an other broker and it works there. Might be a problem with the broker.
