How to debug why I'm loosing connection to my Docker container when VPN is up?

  • 772

I'm using Docker 18.06.1-ce on Ubuntu 16, and I have a container exposing 8012 port. When I do

curl "http://localhost:8012/"

I get response 

Error: Requested URL / not found

But when VPN is up (openfortivpn) after long time waiting I get 

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

When I mess my port number, I instantly get error:

curl "http://localhost:8011/"
curl: (7) Failed to connect to localhost port 8011: Connection refused

How to debug and fix this? Obviously localhost pings, and traceroute to it is one hop.

  1. Advice from here helped, I just added 

    networks:
  default:
    ipam:
      driver: default
      config:
        - subnet: 10.10.11.1/22

    to my docker-compose.yml. The question on how to debug this remains open.
