If a reverse proxy is used to connect to Planon, make sure to configure the RemoteIpValve for the Planon web server. For more information, see:https://tomcat.apache.org/tomcat-10.0-doc/api/org/apache/catalina/valves/RemoteIpValve.html.

Planon includes functionality that returns URLs, and this valve must be configured correctly to ensure that the returned URLs are accurate. The configuration of this valve is specific to your reverse proxy environment and is not part of the Planon installation. As a result, Planon cannot provide the exact configuration parameters required for your setup. Planon can only indicate that this valve must be configured. Determining and applying the correct configuration parameters is the responsibility of the administrator managing the reverse proxy.
