Host name conflict, retrying with hassio-2

It just keeps going and incrementing the host name.
It may be relevant that the docker host itself is running mDNS on 192.168.1.123 (for the purposes of mosquitto container auto discovery as that's not built into the add-on).

Thank you for submitting an issue. This add-on is not tested on a generic Linux Hass.io installation, but it "should" not be a problem. Nevertheless, you have a valid issue on your hands.

Could you be so kind and try stopping the mDNS on the docker host, just for the sake of checking if this is actually causing the issue?

Interesting.. If I disable avahi-daemon on the host it settles on hassio-2 and then continues on to start. Mind you the Home app refuses to accept the pin it generated. I've deleted the entire home bridge folder and restarted so that it would generate a new code but that didn't help. Nothing in the logs about the Home app trying to connect (even with debug on).

@fosty148 Thank you for the report, but unfortunately, that is not similar.
The bug you are reporting is a duplicate of issue #6.
