 Connections to remote servers
 -----------------------------
 
 Some functionalities require the Nextcloud server to be able to connect remote systems via https/443.
 This paragraph also includes the data which is being transmitted to the Nextcloud GmbH.
 Depending on your server setup, these are the possible connections:
 
-- www.nextcloud.com, www.startpage.com, www.eff.org, www.edri.org, nextcloud.com, startpage.com, eff.org, edri.org
+- connectivity.nextcloud.com, www.eff.org, edri.org
 	- `optional (config)`_
 	- for checking the internet connection
 - cloud.nextcloud.com

+System configuration
+--------------------
+
+If you configured restrictions on which domains can be contacted on the internet, you need to add connectivity.nextcloud.com to the allowlist, as it’s now used by default to test internet connectivity instead of www.nextcloud.com. You can also configure any other URL to use in the configuration instead. See :ref:`connections_to_remote_servers`.
