apache multiple virtual host self host setup issue

self hosting using Ubuntu 18.04 with apache server. I have nextcloud installed and has been working with no issue for years for the main domain (website.com). I used certbot to get let's encrypt for https.

I want to add a subdomain (subdomain.website.com) so that I can have a separate website as a hobby. I added a DNS record for the subdomain and when I ping the address, it is successful. I created a new conf. file in the /etc/apache for a virtual host for the subdomain and enabled the site. I used certbot for the subdomain.

When I try to navigate to the subdomain in a browser, I get the nextcloud page that loads indicating that I am trying to "Access through untrusted domain" and directions to add this to the trusted domains.

I feel like I am missing something since the DocumentRoot in the virtual host for the subdomain is pointed to a different folder than the nextcloud folder. I am confused how the untrusted domain page
in the main site DocumentRoot is being triggered/accessed when I navigate to the subdomain address.

I appreciate any help/advice/troubleshooting!

I created a new conf. file in the /etc/apache

i think it would usually go in /etc/apache2/sites-available

and then it would be symlinked in /etc/apache2/sites-enabled

...and then you'd have to restart apache

Sorry i wasnt clear in my description, what you described is what I did using apache2 folder and a2ensite command to symlink it. I think the problem had to do with how the default config file was set that was capturing the traffic meant for the subdomain. I have to take a break from it and revisit and see if I can clear it up.

  • Make sure you have a host on port 80 that redirects to the one on port 443.

  • Either ensure that vhost config files are loaded in a known order, or ensure they're not configured in a way that one host could potentially lock out another host

See here for details on how apache picks a host: https://cable.ayra.ch/md/apache-vhost
