I have it running perfectly with this config:
data_path: /config/zigbee2mqtt
socat:
enabled: false
master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
options: "-d -d"
log: false
mqtt: {}
serial:
port: /dev/ttyUSB0
However, I can’t remember the exact things I changed, so I guess this is as far as I can help.
But if you have a similar setup as me, you can try it out.

Just had to set it up with the same problem.
localhost didn’t work, so had to put in device ip (I’m running a RasPi4).
your_user and your_password is for the HA user set up for MQTT.
This made it work:

So cool, this fixed it for me!!! THANK YOU!!!
Dear all, I have read all the post carefully but still can’t solve my issue.
I can’t maintain my mqtt2zigbee installation up. I always get same error:
Zigbee2MQTT:error 2023-08-19 20:41:52: Error while starting zigbee-herdsman

I think the origin of the error could be here:
Error while opening serialport 'Error: Error: No such file or directory, cannot open /dev/ttyUSB0'
at SerialPort.<anonymous> (/app/node_modules/zigbee-herdsman/src/adapter/deconz/driver/driver.ts:200:28)

I get that error even after following the steps on this feed and can see properly the ttyUSB0 device when listing under dev$ directory.
Let me tell you that I’m running mosquito-mqtt docker with no issues under Synology NAS and that issue is after installing docker of zigbee2mqtt and try to start up the docker service.
Can someone help me to find the solution to my issue?
From the link in your post:
" Error: Resource temporarily unavailable Cannot lock port
This error occurs when another program is already using (and thus locking) the adapter. You can find out which via the following command: ls -l /proc/[0-9]/fd/ |grep /dev/ttyACM0 (replace /dev/ttyACM0 with your adapter port)."
Have you verified that you do not have something else accessing the port? ZHA for example?
serial:
port: >-
/dev/serial/by-id/usb-ITEAD_SONOFF_Zigbee_3.0_USB_Dongle_Plus_V2_20230525094313-if00
adapter: ezsp
worked for me finally
I have been struggling with the problem of inability to start for two weeks. I had over 30 devices configured over Z2M and, perfected the backup and restoration process of Z2M database (the only solution that worked was to delete the configuration files and reinstall Z2M addon). Today I noticed HA while booting said “starting ZHA” 
I removed ZHA and Z2M started up like nothing happened, so if your Zigbee2MQTT fails to start without reason, check your integrations pane and delete ZHA 
Here I am - with a similar problem, desperate for any help available.
I’ve installed Z2M but it fails to start something called “zigbee-herdsman” according to the log:

My ZigBee device is the Sonoff ZbBridge flashed with Tasmota 13.2.0 and the ncp-uart-nsw_6.7.9_115200 firmware. I’m using Blackadders ZHA Template and the Bridge runs just fine and the WebUI console shows all activities. Here’s my Z2M configuation.yaml file:

Yes, thank you - and in addition I had a typo in my IP 
New to Home Assistant here and I am struggling with similar issues, I cannot get Z2M to start no matter what I do.

Well, you guys can add me to the list of people who can’t get this z2m to even start. Here’s pics of my current settings, I just read through most all of this post and tried several of the suggestions for it to still not work.
I tried the mattress server at the ip, nothing. I tried the adapter port on the same line, click save and it moves it back to the next. I tried changing the “DECONZ” in the adapter field to lowercase, nothing…
It has done this EXACT SAME THING on 2 systems I’ve tried to setup, a VM on my Unraid, and this VM on a Proxmox. The same conbee2 being used on both systems (migrating from one to the other).
Look at my post over yours. You set your config in the configuration.yaml file under the zigbee2mqtt directory, not in the GUI.
Where/How do I find that, is that the one in the three dots in the top right of the config page, or is that something else too? Sorry, I’m relying on YouTube videos to try and set this up.
Do I have to copy what you have there (changing fir adapter where necessary), or do I just need certain lines?
