I just found the solution: the first listener seems to always be related to the mqtt protocol. My working configureation specifies two listeners this way:
listener 1883 192.168.222.54
protocol mqtt
listener 8883 192.168.222.54
protocol websockets
and now, it starts with these messages:
1706523693: mosquitto version 2.0.11 starting
1706523693: Config loaded from /etc/mosquitto/mosquitto.conf.
1706523693: Opening ipv4 listen socket on port 1883.
1706523693: Opening websockets listen socket on port 8883.
1706523693: mosquitto version 2.0.11 running
Thank you again for your help.

You appear to be trying to connect to a mosquito server with OT in HTTP mode?
HTTP mode is for talking to HTTP servers, like OT recorder. MQTT mode is for talking to MQTT brokers, like mosquitto.

Yes, you are right. I now corrected the connector to MQTT on the client and configured it for using websocket.
But I am still not able to connect to the server. The new exception is:

so, I double checked my server configuration and it is configured for websocket, but maybe it is running on a different port. The mosquitto log contents are:
1706521211: mosquitto version 2.0.11 starting
1706521211: Config loaded from /etc/mosquitto/mosquitto.conf.
1706521211: Opening ipv4 listen socket on port 8883.
1706521211: Opening websockets listen socket on port 1883.
1706521211: mosquitto version 2.0.11 running
in my configuration I heve these lines:
protocol websockets
listener 8883 192.168.222.54
interesting enough is that if I switch these lines, mosquitto does not start anymore. It gives error message:
1706521555: mosquitto version 2.0.11 starting
1706521555: Config loaded from /etc/mosquitto/mosquitto.conf.
1706521555: Opening websockets listen socket on port 8883.
1706521555: Error: Unable to start any listening sockets, exiting.
So, do the configuration lines require to be put in a specifi order in order to let MQTT use websocket on port 8883?
Thank you very much

The protocol line specifies the listener's protocol, and you define the order as you like.
