Do I need a new TLS certificate if my website is on another host?

The LetsEncrypt integration with MIAB is fantastic. Just for that functionality, I’m considering using my MIAB as my primary nameserver for my domains. So far, I’ve configured my email only domains and have been very pleased with the ease of the setup. Now, I’m ready to test using the MIAB DNS on a domain with a WordPress website.

My question is, do I have to get another certificate directly from LetsEncrypt and install it on the website server, or do I copy the domain certificate from my MIAB and install it on the website server?

LetsEncrypt couldn’t have come at a better time. I’m new to the whole security certificate world, and I need to install certificates on all of my websites to preserve their search rankings. Any insight is appreciated. Thanks in advance.

@jrex I would recommend you to have separate certificates for your domains based on from what server they will be served and reachable online to help certificate(s) renewal process when needed.


Then config. all of them through your MiaB server to manage their DNS’s but set your custom A records pointing to your other web-server IP for 2) and 3) before to order the let’s encrypt certificate for your 1) and the given certificate will be issued for only.

Then go to your web-server and set there the certificate(s) you wish for 2) and 3) from let’s encrypt or wosign-free at your convenience (zz).

Consider this way for additional domains and/or subdomains, too

Doing it that way will save you of headaches at certificate(s) renewal time.

Hope this helps. rgrds

(zz) Unless you’re using a let’s encrypt integrated web admin panel like in your web-server that will help you to manage your domains certificate renewals for your apps. (let’s say joomla, wordpress, drupal, grav … ) I would recommend you to manually set a 1 year (or 2 years) wosign FREE certificate(s) for each one them, instead.
