[HELP] Error "curl: (56) Recv failure: Connection reset by peer" from outside docker container

[technorabilia]

Describe the issue
I get curl: (56) Recv failure: Connection reset by peer when I try to curl from outside the gateway docker container.
Running the curl command from inside the docker container works as expected.

simon@xyz:~/Projects/tb-gateway$ cat docker-compose.yml 
version: '3.3'
services:
    tb-gateway:
        ports:
            - 5000:5000
        volumes:
            - ./logs:/thingsboard_gateway/logs
            - ./extensions:/thingsboard_gateway/extensions
            - ./config:/thingsboard_gateway/config
        container_name: tb-gateway
        restart: always
        image: thingsboard/tb-gateway
simon@xyz:~/Projects/tb-gateway$ curl -H "Content-Type: application/json" -X POST -d '{"sensorName": "SN-001", "sensorModel": "simon"}' http://127.0.0.1:5000/my_devices
curl: (56) Recv failure: Connection reset by peer
simon@xyz:~/Projects/tb-gateway$ docker exec -it 04f sh
# curl -H "Content-Type: application/json" -X POST -d '{"sensorName": "SN-001", "sensorModel": "simon"}' http://127.0.0.1:5000/my_devices

Hi @technorabilia, it happens because you are using localhost for the rest connector, try to use the following config:

{
  "host": "0.0.0.0",
  "port": "5000",
  "SSL": false,
  "security": {
