Error while get mqtt config

EDIT: It’s working now. Thanks to all who helped.

My setup: Home Assistant core-2022.4.5 running on Debian.

Following Mark Watt’s video, last night I flashed this launchpad coordinator to my SONOFF Zigbee 3.0 USB Dongle. No issues.

Both Configuration | Host | Hardware and ls -l /dev/serial/by-id report that the Sonoff dongle is on /dev/ttyUSB0:

$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Apr 19 05:41 usb-0658_0200-if00 -> ../../ttyACM0

Here’s my Zigbee2mqtt configuration:

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

  user: mqtt_user
  password: mqtt_password
  server: mqtt://localhost:1883
serial:
  port: /dev/ttyUSB0
homeassistant: true
frontend:
  port: 8099

Zigbee2mqtt just won’t start. The log reports «Failed to connect to the adapter»:

Thinking that maybe my USB extension cable might be at fault, I also tried plugging the dongle directly into the USB port. No change.

Also re-flashed. Also no change.

Can anyone spot what might be going on?

One ESP32 is in APSTA mode

• AP to other ESP32
• STA to keep it connecting it to the internet

This worked fine after testing it

The mosquitto config file is as follows:-

listener 1883 
allow_anonymous true

And on the other, I am trying to use the example from esp-idf protocol/MQTT/tcp

In idf.py menuconfig :-

• I changed the username and password (ESP32 connection to AP is not an issue reason being I tested the wifi/getting_started/station and it worked fine)
• Default broker URL mqtt://mqtt.eclipseprojects.io

then after erasing flash using esptool.py --port /dev/ttyUSB0 erase_flash

After build I uploaded the code to ESP32 using

idf.py build
idf.py -p /dev/ttyUSB0 flash

And when I monitor it

idf.py -p /dev/ttyUSB0 monitor

It showed the following error

E (562605) esp-tls: couldn't get hostname for :mqtt.eclipseprojects.io: getaddrinfo() returns 202, addrinfo=0x0
E (562605) transport_base: Failed to open a new connection: 32769

Here is the protocol/MQTT/tcp code that I mentioned in question
and APSTA-code as mentioned in question
