How to change email used during Ghost Blog configuration for Let's Encrypt, due to wrong email being used?

Hello,

Thank you for taking your time to help.

I installed the Ghost blogging platform on my Ubuntu 16.04 droplet and everything went smoothly until I used the wrong email for the Let’s Encrypt configuration. (I know I’m an idiot)…

So, I’ve been doing some digging and I found the email listed in the file ‘accounts.conf’ in the directory ‘/etc/letsencrypt’. Would changing this email mean future renewal notices go to this email? As so far I have no emails from Lets Encrypt about the site.

The site does have a working certificate however it shows HTTPS when connecting to it.

Finally, I have also tried the following command with no success:

sudo certbot register --update-registration -m newemail@example.com

I get the following returned from this command:

“Could not find an existing account to update.”

Any help would be great.

Thank you.
