qt.qpa issues

[bentotten]

I am attempting to host this on an EC2 instance, however was running into this error when running build.py

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

There seems to be some code in build.py related to hosting a webserver, but the documentation is not clear - how are you hosting this on https://gravitymoth.com/spall/?
