Sorry for the late reply. I have restarted working on the issue and I found the following error in the log:
Storing nonce: 0003i-Iq3qylgxsh9wyIC8-OR3na3FzWwn0nbs2lFl4SLfY
Challenge failed for domain vpntestalp.com
http-01 challenge for vpntestalp.com
Notifying user:
Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Domain: vpntestalp.com
Type: connection
Detail: Fetching http://vpntestalp.com/.well-known/acme-challenge/uB0BcBjFs2gR6Vn8X5TxAuBqz2nvLNsEAjOUPUQQqBU: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority couldn't exterally verify that the standalone plugin completed the required http-01 challenges. Ensure the plugin is configured correctly and that the changes it makes are accessible from the internet.
