Mhm, netmaker seems to be a nice thing, if you can get it installed, or the caddy getting the damn certificates requested and not triggering the limits of letsencrypt on every try...

We recently switched to using ZeroSSL for certificates, which should not be getting rate limited. Are you still encountering this?

Hi, sorry for taking this long to answer, i wasn´t at home... This was some kind of random. 98% of the times an attempt ended in a failure, because caddy couldn´t get the certificates. Waited 2h tried again, and the caddy logs stated there were to many attempts. Even when i checked the ratelimits for letsencrypt, normaly it should have been fine, but the logs told me otherwise... After some random attempts, it worked. Didn´t change anything, but caddy could request the certificates this time...

Having a similar issue, getting rate limited by zerossl
