docker run fails

[finish06]

After building docker image from Dockerfile, it fails to run. Receive the following output...

npm info it worked if it ends with ok

npm info prestart harmony-api@1.1.0
npm info start harmony-api@1.1.0

Unsure how to progress forward. Recently built this about 30 days ago without any issues.

Can you post your config? It looks like your MQTT broker url might be at issue here.

[finish06]

{
  "mqtt_host": "127.0.0.1",
  "hub_ip": "192.168.1.219",
  "topic_namespace": "harmony.living_room"
}

[maddox]

huh, it looks like maybe you need to specify mqtt:// in the host. try that and see what happens.

[finish06]

"http://" did the trick! Thank you maddox for the assistance.

[maddox]

Great. I need to either change the default config, or just append mqtt:// in the code.
