I've also found that even if you set `retry` to `0`, which is supposed to never retry, it seems to be stuck in retrying to connect:
https://github.com/openstack/oslo.messaging/blob/master/oslo_messaging/notify/notifier.py#L55-L58
It seems that it is stuck to retrying the connection and it doesn't consider EHOSTUNREACH a failure that it should stop retrying on so everything is permablocked.
