HADashboard server not there

I’ve had HA working for a while (ubuntu 18.04, pip3 install in venv) and got AppDaemon running fine (pip3 install, no venv) so it runs Hello.py. But no love from HADashboard. No problem for browsers (Firefox or Chrome) to connect to HA server (:8123), but all browsers time out on the HADashboard server (:5050).

Config file looks like this

appdaemon:
  threads: 10
  disable_apps: 1
  plugins:
    HASS:
      type: hass
      ha_url: http://192.168.xxx.xxx:8123
      token: <very long string>

log:
  errorfile: /var/log/appdaemon.log
  logfile: /var/log/appdaemon.log
  accessfile: /var/log/appdaemon.log

hadashboard:
  dash_url: http://192.168.xxx.xxx:5050
  dash_force_compile: 1

Log looks like this

Never mind. I had to open the port (duh-oh):

sudo ufw allow 5050/tcp
