localhost paths seem hardcoded — impossible to run the app on a remote server

[GentleHoneyLover]

Hi,

I'm running TNoodle-WCA-1.1.2.jar in a container (here's my image: link). It is basically a slight modification of the Dockerfile from your repo. When I deploy the container on localhost (my laptop) it runs just fine and generates scrambles correctly (Screenshot 1 below). However, when I run the same image on my home server (accessed via ip-address:port or through reverse-proxy), the app breaks (Screenshot 2 below). Presumably because localhost paths are hardcoded in the app.

Is that the case? Are there workarounds (like e. g. passing some arguments to java when starting the app)? Or, otherwise, can the app be updated to make all URL paths dynamic rather than static localhost?

Here's how the app starts from within the container: java -server -XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -XX:InitialRAMFraction=2 -XX:MinRAMFraction=2 -XX:MaxRAMFraction=2 -XX:+UseG1GC -XX:MaxGCPauseMillis=100 -XX:+UseStringDeduplication -jar tnoodle-application.jar --online
