Failed to renew -- too many requests

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: sso.aca.k12.or.us

I ran this command:
sudo certbot renew -v

It produced this output:

Certificate is due for renewal, auto-renewing...

Also Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Domain: sso.aca.k12.or.us

It looks like you are affected by a change the Palo Alto company made to their firewalls.

Your symptom is identical to the one below. That is, it responds normally to regular requests but the acme-challenge path is rejected with "reset by peer". Once the firewall is fixed you will have to wait an hour due to your repeated failures
