Regenerate SSL certificate using CERTBOT

[darlington]

After generating ssl for my vps for rankafrica.site and www.rankafrica.site, I wish to change it to generate for my wildcard subdomain (*.rankafrica.site) but it doesn't seem to work (e.g test.rankafrica.site)

I have revoked the existing SSL certificate and I'm trying to regenerate it for my all subdomains in my system but I am getting an error. I don't know how to proceed with this:

Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:
Domain: rankafrica.site
Type: unauthorized
Detail: No TXT record found at _acme-challenge.rankafrica.site

Hint: The Certificate Authority failed to verify the manually created DNS TXT records. Ensure that you created these in the correct location, or try waiting longer for DNS propagation on the next attempt.

Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

Please do not revoke unneeded certificate, just disregard it. Revoking certificate uses precious resources.

Did you add the requested TXT record into the DNS of rankafrica.site domain? If yes, you have to wait enough time that the changes propagates to all authoritatve name servers before continuing with certbot.

authenticator: manual

You might want to consider using the Welcome to certbot-dns-linode’s documentation! — certbot-dns-linode 0 documentation DNS authenticator instead of the manual plugin.
