[Bug]: no frontend reachable

What happened?

I use zigbee2mgtt in a docker container. The docker container is running with portainer in an lxc container in Proxmox. After Starting up, I am not able to access the frontend.

configuration.yaml

permit_join: true
mqtt:
  base_topic: zigbee2mqtt
  server: mqtt://192.168.178.203:1883
serial:
  port: /dev/ttyACM0
  adapter: zstack

    friendly_name: '0xd0cf5efffe1f9850'
  '0xec1bbdfffea95c60':

my docker compose file

I wonder if there should be a logline like this? (But is not) "Zigbee2MQTT:info 2022-04-29 09:36:17: Started frontend on port 0.0.0.0:8080"

Doing telnet on the dockerhost is successful, but the connection is closed immediately

Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

Curl does not get a connection from the dockerhost

curl: (56) Recv failure: Connection reset by peer

This is my zigbee device

usb-1a86_USB_Serial-if00-port0

Bus 002 Device 003: ID 1a86:7523 QinHeng Electronics CH340 serial converter

What else can I try? Since I am a newbee to using docker, I am not totally sure about networking, but also tried bridge mode with no success. Thank you for your help!

What browsers are you seeing the problem on?

Chrome
