Question

www alias throwing ssl error --ubuntu server 1 click WP

Hi I have setup a ubuntu 1-click WP server, and while setting up Lets Encrypt I only set it up for domain.com and not for www.domain.com alias and www.domain.com is redirected to https://domain.com. Now for some user when they open https://www.domain.com it shows them invalid ssl cert error. Can I still setup Lets encrypt for www ? or i will need to remove the non ssl first? and if so how can it be removed?

Thanks

Hello, @Sunny9616

You can revoke/delete the current SSL Certificate and then issue another one but include the www version as well.

To revoke the SSL:

  1. sudo certbot delete –cert-name example.com

To obtain a new SSL:

  1. sudo certbot --apache -d your_domain -d www.your_domain
