Can't figure how to add a ProxyPass in Apache to a Nextcloud instance at a local IP

ℹ️ Support
#1

I have a Raspberry Pi serving a couple of static websites through Apache and doing some other stuff.

Now I’ve been gifted another Raspberry, so I installed NextCloudPi on it, and I would like to redirect a new subdomain (something like cloud.domain.com) from the first Raspberry to the new. I tried adding and enabling the following cloud.conf file in my main pi Apache’s sites-available directory but that breaks some of my other domains and does not redirect to the Nextcloud instance. What is the correct way of redirecting that subdomain?

<VirtualHost *:443>
    ServerName cloud.domain.com
    ServerAlias cloud
    ProxyPass / https://192.168.1.200:443
    ProxyPassReverse / https://192.168.1.200:443
    ProxyPreserveHost On
    ProxyPass /.well-known/acme/ !
</VirtualHost>

Should I also redirect port 80? Also, I would like to use ssl with lets-encrypt for Nextcloud, as I am doing with the main domain. Should I just run certbot on the nextcloud pi instance as I did on the main pi, or is it more complicated than that?

Have you actually enabled the modules of your Apache for operating such a proxy?

You can check the currently enabled modules with the following command:

apachectl -M

Does the listing include a module proxy and a proxy_http?

#3

Yes, it shows both:

  • proxy_module (shared)
  • proxy_http_module (shared)

Are we talking about the main Apache server, right? Where the proxy cloud config lives.

#4 
a2enmod proxy
a2enmod proxy_http
a2enmod proxy_ajp
a2enmod rewrite
a2enmod deflate
a2enmod headers
a2enmod proxy_balancer
a2enmod proxy_connect
a2enmod proxy_html


service apache2 restart


ProxyPass / http://192.168.1.200:443/
ProxyPassReverse / http://192.168.1.200:443/

I get the same result: the cloud subdomain is not being relayed, and two of my domains break. How can I debug this?

#6

What’s happening with your sites on the first RPI?

One of them (the one sharing domain with ncp) is OK, the other two just won’t load as soon as I run a2ensite. They seem to load infinitely but they never end loading. The screen is blank.
