Issue with NextCloud(Pi) on Apache2 webserver

Hi!

I’m in the process of setting up a nextcloud webserver on my Raspberry Pi, currently, and it’s been going okay so far. I am trying to set it up for external use, and have gotten that working with a DNS provider. But the issue I am having is quite weird. The site was working fine, being accessible from the URL I have, but there was no SSL set up yet. So I set up SSL, and currently for the use of the https:// address, on port 443, but for some weird reason any “dynamic” content on the site is disabled.

/etc/apache2/sites-enabled/nextcloud.conf
<VirtualHost *:80>
  ServerName cloud.<domain>

  Redirect permanent "/" "https://cloud.<domain>"
</VirtualHost>

<IfModule mod_ssl.c>
  <VirtualHost *:443>
    DocumentRoot /var/www/nextcloud
    ServerName cloud.<domain>

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

    SSLEngine on
    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLProtocol TLSv1.2 TLSv1.3
    SSLCertificateFile /etc/letsencrypt/live/cloud.<domain>/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/cloud.<domain>/privkey.pem

    <Directory /var/www/nextcloud/>
      Options +FollowSymlinks
      AllowOverride All
      <IfModule mod_dav.c>
        Dav off
      </IfModule>
      LimitRequestBody 0
      SSLRenegBufferSize 10486000
    </Directory>
  </VirtualHost>
</IfModule>

The site looks like the following, while it looked normal before, while still being accessed externally.

Any ideas as to what could be the cause of this?

Bump. Would really love it if anyone have any comments at all regarding this.
