Just a wild guess, because I am as far from a Zigbee expert as Grandma is with Home Assistant.
Try the real IP address. My configuration has this:
server: mqtt://192.168.1.124:1883
(My MQTT broker is on a Raspberry Pi and my Home Assistant is on an Intel NUC).

just tested (using mqtt://“the pi IP where everything is running”)

server: mqtt://192.168.1.195:1883

same error

Zigbee2MQTT:info  2023-01-10 00:25:11: Connecting to MQTT server at mqtt://192.168.1.195:1883

My guess would be you followed one set of instructions to configure the mosquito add-on and another for your Z2M integration, and the username and password for MQTT don’t match.

The username and password in Z2M:

base_topic: zigbee2mqtt
server: mqtt://192.168.0.100:1883
user: your_username
password: your_password

must match that configured in MQTT:

- username: your_username
  password: your_password

and also in the MQTT integration under broker settings.

Don’t know, if this is a copy 'n paste error or even if it does matter, but „Password:“ should be lower cased.

I can’t tell you if make or copied that error at the beginning but then it has ben invisible to me even if in front of my face for one week! Thank you!

Just to clarify to whoever will read this post in the future looking for a fix like I did with others here the working zigbee2mqtt configuration:

mqtt:
  base_topic: zigbee2mqtt
  server: mqtt://192.168.1.195:1883
  user: bot
  password: xxxxxx
7

They match it was the upper case of the P in “password”
Anyhow thank you!
