Keep getting the error: Renewing [www.xx.com]: acme: error: 429

[job_noam (Noam)]

I keep getting this errors on a lot of domains on our servers and it’s looks nothing is renewed:
[ERROR] Renewing [www.xx.com]: acme: error: 429 :: POST :: https://acme-v02.api.letsencrypt.org/acme/new-order :: urn:ietf:params:acme:error:rateLimited :: Error creating new order :: too many new orders recently: see Rate Limits - Let's Encrypt, url: ; trying again in 10s

What can be the problem?

Thanks

It’s pretty clear what it’s telling you. You hit the rate limits.

You didn’t fill out the thread template, so we can’t help any more than that.

Aye, all we can do is give vague advice here.

Double check networking, double check DNS, check earlier logs.

Rate limits are not usually the root problem, they’re a symptom. Earlier logs will likely have actual challenge errors. We see this problem most commonly when people fail to configure their environment properly for Caddy to complete challenges and then configure it to auto-restart, ignoring errors and hammering LetsEncrypt’s servers.
