Ensure scheme is set accurately
Beschreibung
The scheme attribute is used to indicate to callers of request.getScheme() which scheme is in use by the Connector. Ensure the scheme attribute is set to http for Connectors operating over HTTP. Ensure the scheme attribute is set to https for Connectors operating over HTTPS. For every Connector: SSLEnabled="true" requires scheme="https"; other connectors must have scheme unset or "http". Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored.

So wird behoben
Behebungsmethode: Anleitung oder Infrastruktur-Patch
Set scheme="https" on TLS connectors and scheme="http" (or none) on plain HTTP connectors in server.xml. Restart Tomcat afterwards.
