Running Nuclos behind a reverse proxy
Run Nuclos behind an Apache reverse proxy – AJP connector and vhost configuration for rich and web client.
HOW-TO ADMINISTRATOR UPDATED: JUL 2026 APPLIES TO NUCLOS 4.2026.X
On this page
Tomcat can run behind an Apache reverse proxy – e.g. when Nuclos should be served over HTTPS but port 443 is already taken.
Configure Tomcat
The AJP connector must be enabled. Since Nuclos 4.8.0 this is done directly in the installer (step „Server configuration“) – no manual Tomcat change needed.
AJP
The AJP protocol is mandatory, otherwise the access path to the Nuclos instance is not mapped correctly.
Apache for the rich client (Java Web Start)
Create a vhost and adjust the domain:
