I had port 80 and 443 forwarded before.. then I removed 80
now, an attempt to renew looks like:
sudo certbot renew Cert is due for renewal, auto-renewing... Plugins selected: Authenticator apache, Installer apache Renewing an existing certificate Performing the following challenges: http-01 challenge for [mydomain] Waiting for verification... Challenge failed for domain [mydomain] http-01 challenge for [mydomain] Cleaning up challenges Attempting to renew cert ([mydomain]) from /etc/letsencrypt/renewal/[mydomain].conf produced an unexpected error: Some challenges have failed.. Skipping. All renewal attempts failed. The following certs could not be renewed: /etc/letsencrypt/live/[mydomain]/fullchain.pem (failure)
What is the correct way to make this process switch to the working HTTPS port ?
