Do you see an area that can be clarified or expanded, a technical inaccuracy, or a broken link? Please describe.
The documentation page describing the integration of Authentik and Nextcloud lacks key information, at least for the OIDC part. While following this documentation, I encountered a problem while setting up OIDC within Nextcloud. Specifically, Nextcloud was not able to establish any connection with the Authentik server unless the config.php file of Nextcloud included the line 'allow_local_remote_servers' => true.

It seems that this problem has already been reported in several other places, for example:

• https://help.nextcloud.com/t/oauth2-openid-discovery-endpoint-nextcloud-omits-to-connect-via-https-and-uses-port-80/216182
• Nextcloud claims "Could not reach the OpenID Connect provider.", keycloak logs says ClientID=null nextcloud/user_oidc#555
• Could not update the provider: The discovery endpoint is not reachable. nextcloud/user_oidc#803
• https://www.schiessle.org/articles/2023/07/04/nextcloud-and-openid-connect/

Provide the URL or link to the exact page in the documentation to which you are referring.

Describe the solution you'd like
The section of the documentation mentioned above should include at least a sentence, describing that problems during setup in Nextcloud may occur if the variable allow_local_remote_servers in config.php is not set to true.
