Unable to load container

Hello,

I am unable to load the gn3 container by using docker on a remote machine. When I try to launch the server web page, I get nothing "site can't be reached" error on the browser. eg http://192.168.3.50:3030 - nothing opens up.

Expected response: should be able to open up GNS3 on a remote site using a custom port (3080 or any other)

This is my docker compose file:

services:
    gns3-server:
      image: jsimonetti/gns3-server:latest
      container_name: gns3
      privileged: false
      environment:
      - BRIDGE_ADDRESS=172.21.1.1/24
      volumes:
       - ./data:/data
      network_mode: host

---

Log file attached gns3logs.txt From the logs, it looks like this is the culprit:

brctl: bridge virbr0: Operation not permitted
ip: ioctl 0x8913 failed: No such device
ip: can't find device 'virbr0'
getsockopt failed strangely: Operation not permitted

I am not entirely sure, but I think privileged mode is required when using host networking. Could you give that a go?

Besides that, make sure there are no firewalls in between. This container will require you to open ports yourself.
