MQTT seems doesn't work

[4sp3c]

Good morning everyone. I just installed sonoff coordinator and I have 2 sonoff probe. I flashed the coordinator with the last firmware and I associated a probe correctly (I can see that on configuration.yalm)
I installed mosquitto and I running on my pc. I have this configuration

for zigbee:
homeassistant: false
permit_join: false
mqtt:
base_topic: zigbee2mqtt
server: mqtt://localhost:1883
serial:
port: /dev/ttyUSB1
advanced:
homeassistant_legacy_entity_attributes: false
legacy_api: false
log_level: debug
device_options:
legacy: false

for MQTT
persistence_location /var/lib/mosquitto/
log_dest file /var/log/mosquitto/mosquitto.log
listener 1883
allow_anonymous true

I started with sudo privileges zigbee2mqtt with
sudo npm start

the system started and I had this log

Zigbee2MQTT:debug 2021-12-06 10:22:45: Loaded state from file /opt/zigbee2mqtt/data/state.json

and stop. The logs finished here and MQTT is not connected. How can I solve it?
Any helps will be appreciated.

Hi @rommelfreddy, if I remember well, I changed only localhost with 127.0.0.1
try and give me a feedback

[rommelfreddy]

i figured out, that the protocol type "websockets" will produce the error, that the port binding of mqtt will only for the ipv6 address.
After changing it to "mqtt" the problem is resolved and the port got also binded for ipv4.

Got the "websockets" value from two tutorials.
I am honest - i have no idea where the difference is.
Never mind - now it works like expected.
