Vroom error - conncetion refused: nominatim

Question

I am trying to setup a local Vroom instance using docker-compose (following this tutorial). Here is my docker-compose file:

version: "3"
services:
    osrm:
        container_name: osrm
        image: osrm/osrm-backend
        restart: always
        ports:
            - "5000:5000"
        volumes:
            - /home/florian/Documents/repo/vroom-test:/data
        command: "osrm-routed --max-matching-size 1000 --max-table-size 1000 --max-viaroute-size 1000 --algorithm mld /data/sachsen-anhalt-latest.osrm"
        networks:
            tsp_network:
                aliases:
                - osrm
    vroom-backend:
        container_name: vroom-backend
        image: vroomvrp/vroom-docker:v1.11.0
        restart: always
        ports:
            - "3000:3000"
        environment:
            - VROOM_ROUTER=osrm 
        depends_on:
            - osrm
        networks:
            tsp_network:
                aliases:
                - vroom-backend
    vroom-frontend:
        container_name: vroom-frontend
        image: iedmrc/vroom-frontend
        restart: always
        ports:
            - "9966:9966"
        depends_on:
            - osrm
            - vroom-backend
        networks:
            tsp_network:
                aliases:
                - vroom-frontend
networks:
  tsp_network:
      driver: bridge

Everything starts up fine and seems to work, but when I tried to use the vroom-frontend, it does not work and I get the following error:

I think that happens because nominatim blocked my IP-address (too many requests) - is this supposed to happen? Shouldn't work Vroom without this external service?

I am also getting the following error:

Here is my input file, which works fine when used on the Vroom demo:

Here is how it should look (using the official Vroom demo server):
