This is not a bug, the gateway ping timesout because the gateway isn't reachable.

And the continuous register challlenges just mean you're online on the internet and those are people attempting to compromise your server and make free calls. To fix that you need to apply ACLs on your firewall to restrict access to subnets you want to allow or you need to look at something like fail2ban to block people that attack you.
