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: www.cefeel.com

I ran this command: certbot --apache

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

1: www.cefeel.com

Select the appropriate numbers separated by commas and/or spaces, or leave input

Congratulations! You have successfully enabled https://www.cefeel.com

IMPORTANT NOTES:

  • Congratulations! Your certificate and chain have been saved at:

    Your cert will expire on 2021-06-19. To obtain a new or tweaked

Hi @sksamal

your configuration looks buggy, because Certbot shows only one domain name.

What says

apachectl -S

You should add cefeel.com to the existing certificate you created, and a redirect to whichever domain you want users to end up at. Currently, only your page at cefeel.com shows up. (Beautiful photo at the top! :smiley: ) I see you have a redirect from the www version to the non-www version (which is where your content resides).

Run Certbot again using
certbot --cert-name www.cefeel.com -d cefeel.com,www.cefeel.com
This will add the non-www domain to your cert.
