Neo-scan cannot sync with Neo-Go node

[aprasolova]

I have a neo-go node of version 0.74.1-pre-47-g396c78c and I'm trying to connect neo-scan to this node.

I run neo-scan with docker-compose. The compose file is:

version: '2.4'

services:
  neo-scan:
    container_name: neo-scan
    depends_on:
      - postgres
    environment:
      DB_DATABASE: neoscan_prodv
      DB_HOSTNAME: localhost
      DB_PASSWORD: postgres
      DB_USERNAME: postgres
      NEO_SEEDS: >-
        http://127.0.0.1:30333
      PORT: 4000
      REPLACE_OS_VARS: 'true'
    healthcheck:
      interval: 30s
      retries: 3
      start_period: 20s
      test:
        - CMD
        - bash
        - '-c'
        - exec 6<>/dev/tcp/127.0.0.1/4000
      timeout: 10s
    image: 'cityofzion/neoscan:latest'
    network_mode: host
    restart: always

  postgres:
    container_name: postgres
    environment:
      POSTGRES_DB: neoscan_prodv
      POSTGRES_PASSWORD: postgres
      POSTGRES_USER: postgres
    image: 'library/postgres:12-alpine'
    network_mode: host
    restart: always

Neo-Go's config file, protocol.privnet.yml, looks so:

The error that neo-scan writes to log:

2020-04-06 09:16:34.656 [error] [[email protected]] error while downloading block {2454, :exit, {:timeout, {Task.Supervised, :stream, [60000]}}}

and so on and so forth for every block.

Looking into neo-go logs, I see that neo-scan sends a getapplicationlog RPC request, but there is no transaction ID in it, but '00' instead.

Neo-Go privnet consensus node runs at 85.143.219.93:30333 and accepts RPC requests from internet, since it might be useful for debug.

@adrienmo do you have any ideas?
