Blocked by a firewall? and reached limit of failures

My domain is:
I ran this command:
certbot renew --no-random-sleep-on-renew
It produced this output:
Saving debug log to C:\Certbot\log\letsencrypt.log

Processing C:\Certbot\renewal\

Renewing an existing certificate for
Failed to renew certificate with error: urn:ietf:params:acme:error:rateLimited :: There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see Rate Limits - Let's Encrypt

All renewals failed. The following certificates could not be renewed:
C:\Certbot\live\\fullchain.pem (failure)

1 renew failure(s), 0 parse failure(s)

My web server is (include version):
Apache 2.4
The operating system my web server runs on is (include version):
Windows 10 Pro 21H1
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
certbot 1.20.0

Before the limit error I was getting this output:

Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Type: dns
Detail: DNS problem: NXDOMAIN looking up A for - check that a DNS record exists for this domain

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

My guess is that my firewall was blocking the incoming connection, but I'm not sure, bc ports are open, I host a website and it's reachable from outside

  1. I think I reached a failure limit, what can I do to fix it?
  2. What rule should I add to the windows firewall to make certbot

I noticed just now NXDOMAIN error, should I change my dns provider?

You need ensure they can resolve your name to your IP.
[moving to another provider might not fix that problem - or it might]
