I've been stuck on this for awhile. Any help will be appreciated. 
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: pulserank.info
I ran this command: sudo certbot install --cert-name pulserank.info
It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Deploying certificate
Successfully deployed certificate for pulserank.info to /etc/apache2/sites-available/FlaskApp-le-ssl.conf

My web server is (include version): Apache2: Server version: Apache/2.4.41 (Ubuntu)
Server built: 2023-03-08T17:32:54
The operating system my web server runs on is (include version): Ubuntu 20.04.6 LTS
My hosting provider, if applicable, is: Google Compute Engine
I can login to a root shell on my machine (yes or no, or I don't know): yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.6.0
Some other commands I ran to try and debug myself and their outputs:
sudo tail -f /var/log/letsencrypt/letsencrypt.log
