Application server will not bind web interface on virtual machine

ChirpStack Application Server
1

I have Ubuntu 18.04 running on a virtualbox. chirpstack-application-server is running, but the web interface is inaccessible. From netstat, it appears that the service is not even binding the port 8080 on anything.

# This is the API and web-interface exposed to the end-user.
    [application_server.external_api]
    # ip:port to bind the (user facing) http server to (web-interface and REST / gRPC api)
    bind="0.0.0.0:8080"

# ps aux | grep chirp

Have you checked the logs? That is usually a first good step to debug issues :slight_smile:
