Page isn't redirecting properly when second virtual host added

I have followed the instructions here https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-ubuntu-18-04 to create another virtual host on apache so that I could host two websites from one droplet. I have created a conf file is /sites-available/ like this:

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerAdmin webmaster@localhost

        ServerName diffuse-mode.tk
        ServerAlias www.diffuse-mode.tk

        DocumentRoot /var/www/html2

        <Directory /var/www/html2/>
            Options FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =www.diffuse-mode.tk [OR]
RewriteCond %{SERVER_NAME} =diffuse-mode.tk
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

SSLCertificateFile /etc/letsencrypt/live/diffuse-mode.tk/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/diffuse-mode.tk/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

Here is the conf file for the original site:

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerAdmin webmaster@localhost

        ServerName petersenglish.nyc
        ServerAlias www.petersenglish.nyc

        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/petersenglish.nyc/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/petersenglish.nyc/privkey.pem
</VirtualHost>
</IfModule>

These conf files were modified by letsencrypt. The other website, which was on there already before I tried to set up this one, already had a letsencrypt SSL certificate. I added one to the new site as well. Right now it is just a simple index.html file in html2. The original website is wordpress.

The problem is that when I go to diffuse-mode.tk, I get the following error from the browser:

**The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.**

At first, before I put in an A record for www, it would go to www.diffuse-mode.tk and say the site is not found.

How can I get diffuse-mode.tk to go to html2?
