Site unreachable after certbot installation

[der_spotter]

Hi, I just ran certbot and now my site is unreachable. no http and not https. it just doesnt load, no direct error message.

My domain is: test.designing-history.world

I ran this command: sudo certbot --apache

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

---

1: test.designing-history.world

Select the appropriate numbers separated by commas and/or spaces, or leave input
blank to select all options shown (Enter ‘c’ to cancel):
Cert not yet due for renewal

You have an existing certificate that has exactly the same domains or certificate name you requested and isn’t close to expiry.
(ref: /etc/letsencrypt/renewal/test.designing-history.world.conf)

What would you like to do?

---

1: Attempt to reinstall this existing certificate
2: Renew & replace the cert (limit ~5 per 7 days)

---

Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel): 1
Keeping the existing certificate
Deploying Certificate to VirtualHost /etc/apache2/sites-enabled/drupal-le-ssl.conf

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

---

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you’re confident your site works on HTTPS. You can undo this
change by editing your web server’s configuration.

Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel): 1

HTTPS uses TCP port 443 (and some newer implementations now also use UDP port 443).
Your system is NOT responding to TCP port 443 connections.
