Failed to start zigbee

[eiger3970 (K)]

Hello, I just installed my 1st Home Assistant 11.5 on a hypervisor (VMM 4.0.0) with the USB passed through to the KVM and it runs nicely.
Unfortunately, adding a Zigbee USB stick to a Zigbee temperature sensor has brought up error:
Fails to connect.

This is the guide I followed.
This is my troubleshooting as per the MQTT help document:
Check Home Assistant → Terminal →
$ ls -l /dev/serial/by-id/ → select Enter → /ttyACM0.
$ test -w /dev/ttyACM0 && echo success || echo failure → select Enter → success.

Beside this you need to create a config file to tell type of USB dongle etc.

Yes, I do have these configurations added, but the error appears.
I noticed the line serial line went blank, so I retyped in the configuration and restarted.
Now the log shows this, but no connection? Note this forum’s code colours don’t match the Home Assistant log colours. Lines 1-3 should have green colour after INFO:

Just changed the configuration as per a more recent video:
Configuration: (hidden code text shows: V2_20231216093416-if00)

the mqtt port should be 1883 or 8883.

Thank you, that fixed the error
