WebUI crashing on startup [fixed?]

Running MineOS in a TrueNAS jail, and the WebUI wont start, when I go to the site it says that it wont respond

I have tried to do some testing to figure out what is not working, but my JS knowledge is small
I think it may either be NPM being incorrectly configured, or some kind of local variables mis-configured, this is otherwise a clean install

if someone could let me know what log files to check (Im not sure which one has the info I need) I will update iwth logs

I just did a clean reinstall, I think it might actually be a problem with the minecraft world files
