Container unhealthy and working intermittently

[BlaiseLebreton]

Hello !

Using the following docker-compose :

version: "3.4"
services:
  vpn:
    container_name: vpn
    image: dperson/openvpn-client:latest
    cap_add:
      - net_admin # required to modify network interfaces
    restart: unless-stopped
    volumes:
      - /dev/net:/dev/net:z # tun device
      - ${ROOT}/config/vpn:/vpn # OpenVPN configuration
    security_opt:
      - label:disable
    command: '-f "" -r 192.168.1.0/24' # enable firewall and route local network traffic

I'm having mixed results. Sometimes it works perfectly for a few days and then for some reasons it stops working for another few days.

The logs are here : _vpn_logs.txt

The container is marked as unhealthy : curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api.ipify.org:443

However I can curl the api without https :

Any idea what is happening ?

I just realized that I can't ping anything from inside the container :

bash-5.1# ping google.com
