Yesterday I have noticed that my Kubernetes cluster is not issuing any new certificates. On further investigation, I found the following error in the logs:
Failed to verify ACME account: acme: urn:ietf:params:acme:error:rateLimited: Your IP, x.x.x.x, has been blocked due to ridiculously excessive traffic. Once this is corrected you may request this be reviewed on our forum https://community.letsencrypt.org
And I see the same error since 31 days which means since Jan 29th 2019 this issue persists and unfortunately, I noticed this now.
I have found the following issue on Github that limit the number of requests to ACME servers which might be the solution for the excessive traffic from any IP:
So, I have upgraded my cert-manager to the latest. However, until my IP has been unblocked I will not be able to issue new certificates through my cert-manager.
Can someone on the community help me unblock my IP address?
