Hi can you try using this docker image and see if this resolves your issue:

foxxmd/multi-scrobbler:experimental

Have you made any changes to your network recently? Anything like a new router, setting up pihole or changing dns at the docker, host, or router level?

I can't reproduce your issue and haven't had any other users report this. The error you receiving is due to a DNS server not responding which is very likely outside of the control of multi-scrobbler https://github.com/nodejs/node/issues/15780#issuecomment-334496907

If you are using a file-based configuration (config.json or lastfm.json as opposed to ENV) you can increase the number of polling/retry attempts -- by specifying maxPollRetries or maxRequestRetries in the data property -- and see if that solves things for you:

lastfm.json example:

{
  "clients": [
    "MyMalojaConfig",
  ],
  "data": {
    "clientId": "787c921a2a2ab42320831aba0c8f2fc2",
    "clientSecret": "ec42e09d5ae0ee0f0816ca151008412a",
    "redirectUri": "http://localhost:9078/callback",
    "maxPollRetries": 3,
    "maxRequestRetries": 2
  },
  "name": "MyLastFmClient"
}

@elit3ge please try pulling the latest foxxmd/multi-scrobbler:experimental image and see if that makes a difference.

The DNS fix is included in 0.6.0
