Apache2 bad subdomain name configuration

🚧 Installation
1

Hello community,

I’m having trouble configuring my new subdomain name correctly on Apache2/Archlinux VPS.
I have a domain name called example.org that points on /srv/http/.
I also have a subdomain name (DNS entry A) called nextcloud.example.org that I would like to point on my nextcloud folder “/usr/share/webapps/nextcloud/”.
I can currently get access to nextcloud via an alias : example.org/nextcloud/, but not with the new subdomain name. My browser says “bad redirection”.

My config files :
# /etc/httpd/conf/extra/nextcloud.conf

Alias /nextcloud "/usr/share/webapps/nextcloud/"
<Directory /usr/share/webapps/nextcloud/>
  Require all granted
  AllowOverride All
  Options FollowSymLinks MultiViews

  <IfModule mod_dav.c>
    Dav off
  </IfModule>

</Directory>

<VirtualHost *:80>
   Redirect permanent / https://nextcloud.example.org/
</VirtualHost>

<VirtualHost *:443>
  DocumentRoot "/usr/share/webapps/nextcloud/"
  ServerName nextcloud.example.org 
    ErrorLog /var/log/httpd/nextcloud.info-error_log
    CustomLog /var/log/httpd/nextcloud.info-access_log common

  <Directory /usr/share/webapps/nextcloud/>
    Require all granted
    AllowOverride All
    Options FollowSymLinks MultiViews

    <IfModule mod_dav.c>
      Dav off
    </IfModule>

    <IfModule mod_headers.c>
      Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"
    </IfModule>

  </Directory>
RewriteEngine on
RewriteCond %{SERVER_NAME} =nextcloud.example.org
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

SSLStaplingCache "shmcb:logs/ssl_stapling(32768)"

Is something wrong with my config files? It worked for a while but I tried to follow all the security recommandations (activating https etc.) on nextcloud guidelines, that’s when my subdomain name messed up.

Thank you for your help.

If your “Alias /nextcloud” points to -->
“/usr/share/webapps/nextcloud/” and your "DocumentRoot is also “/usr/share/webapps/nextcloud/” your server might miss a "/nextcloud/ inside de DocumentRoot directory…or your alias could be “/” . Not sure about it. Check the logfile :wink:
