Newly created SSL certificate will not update

I have a self-hosted website and recently my SSL certificate expired. Tried creating a new one with the command sudo certbot certonly -d 'example.com,*.example.com' --manual --preferred-challenges dns. The command runs without problems producing the following errors, producing the following output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for example.com and *.example.com

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/example.com/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/example.com/privkey.pem
This certificate expires on 2023-05-09.
These files will be updated when the certificate renews.

NEXT STEPS:
- This certificate will not be renewed automatically. Autorenewal of --manual certificates requires the use of an authentication hook script (--manual-auth-hook) but one was not provided. To renew this certificate, repeat this same certbot command before the certificate's expiry date.

But still, it doesn't work, when I check it with eg. https://www.sslshopper.com/ , it still shows the expired certificate. I waited more than a day and it's still nothing. Sidenote: I don't have any TXT records set up, certbot didn't ask me to set one up, like last time
