Note: x.duckdns.org points to an internal IP via internal DNS settings, the same thing happens if I use an IP address.

To Reproduce

1. Have HA setup on a different server/docker etc
2. Connect via the package to HA.
3. Restart HA
4. Watch for NR to restart (if you have restart-unless-stopped etc setup for docker).

Expected behavior

Error messages only, then a connection followed by working system :)
