Causing significant load on Traefik for no reason.

Problem 1: Stop the spam if api is down
Problem 2: Use the internal dns instead of external DNS roundtrip

[MrRowey]

@Brutus5000 is this still an issue ?

[Brutus5000]

As far as I know yes.

Problem 1: Stop the spam if api is down

cannot reproduce this anymore, can you guide me?

Problem 2: Use the internal dns instead of external DNS roundtrip

this can be fixed on the server via extra_hosts or similar config
