Does .htaccess work?

Philip_Colmer · March 4, 2020, 3:50pm

I don’t understand the question. I’ve added .htaccess to the root of the webserver per the documentation but the server is still reporting that the discovery URLs aren’t working.

Sanook · March 4, 2020, 7:24pm

Is you webserver configured to allow .htaccess files?

Philip_Colmer · March 5, 2020, 9:13am

Thank you for the clarification.

Just to be sure, I extended the Apache configuration file to include the appropriate configuration:

Alias /nextcloud "/var/www/nextcloud/"

<Directory /var/www/>
  Require all granted
  AllowOverride All
</Directory>

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

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

</Directory>

I’ve restarted Apache but to no avail.

The error log is only showing this when I ask NC to update the warnings page:

AH01797: client denied by server configuration: /var/www/nextcloud/data/.ocdata

The “other_vhosts_access” log is showing that an error code is returned when the “well known” URLs are queried:

"PROPFIND /.well-known/caldav HTTP/1.1" 405
"PROPFIND /.well-known/carddav HTTP/1.1" 405

I ended up solving this by moving the NC installation to the root directory.
