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](https://crt.sh/?q=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: [www.theweereview.com](http://www.theweereview.com) I ran this command: sudo certbot renew It produced this output: * * * Processing /etc/letsencrypt/renewal/theweereview.com.conf * * * Renewing an existing certificate for [theweereview.com](http://theweereview.com) and [www.theweereview.com](http://www.theweereview.com) Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems: Domain: [www.theweereview.com](http://www.theweereview.com) Type: unauthorized Detail: 2a03:b0c0:1:d0::beb:1: Invalid response from [http://www.theweereview.com/.well-known/acme-challenge/Fhnr6JRpRrzqHmZjtYGmwrgQVhcmrcaVN3SmRxwDTck:](http://www.theweereview.com/.well-known/acme-challenge/Fhnr6JRpRrzqHmZjtYGmwrgQVhcmrcaVN3SmRxwDTck:) 404 Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet. Failed to renew certificate [theweereview.com](http://theweereview.com) with error: Some challenges have failed. * * * The following certificates are not due for renewal yet: /etc/letsencrypt/live/theweereview.com-0001/fullchain.pem expires on 2023-06-15 (skipped) All renewals failed.
