Hi, we’ve developed a Vaadin Spring Boot app that works perfectly when we run it as is, but when we tried to run it behind Apache Proxy (so that requests to http://website/vaadin-app/ are forwarded to http://website:8080), we’ve got a problem: UI is rendered successfully, but the data can’t be fetched from the server. The error is: The requested URL /vaadinServlet/UIDL/ was not found on this server.
This is exactly how we worked it around at the moment. But it’s just a work-around and not a real solution since we are adding some additional and unnecessary configuration to the Apache’s setup. And what we want to achieve is to configure Vaadin and/or Spring somehow so it sends requests to corrects paths (relative ones).
