According to the instructions at https://plantuml.com/starting, after starting PlantUML Docker image plantuml/plantuml-server:jetty, you should navigate to http://localhost:8080/plantuml in your web browser. However, I get a 404. If I instead go to either http://localhost:8080/uml or http://localhost:8080, everything works fine and I can create PlantUML diagrams. Can you reproduce the bug or is it just my machine?
