Blank page when loading in nginx with non-standard port

[SimonHova]

I host my ampache server on a non-standard port (5006), so I would access it at http://xxx.xxx.net:5006/ample . When I get there, I just get a blank page, and the line in page source looks for a link that isn't there:

<link rel='stylesheet' href='//xxx.xxx.net:5006/ample/public/build/bundle.css'>`

Interestingly, when trying to load the stable demo override line by uncommenting the line: detectedURL = "https://demo.ampache.dev"; from ample/src/stores/server.js I now get an entry in my nginx error log: 2022/09/01 08:15:37 [error] 19063#19063: *209 open() "/opt/ampache/public/ample/public/build/bundle.css" failed (2: No such file or directory), client: xx.xx.xx.xx, server: xxx.xxx.net, request: "GET /ample/public/build/bundle.css HTTP/1.1", host: "xxx.xxx.net:5006"

Could the port number in the url be throwing the script off? Or is there more rewriting that needs to be done in the nginx config file? Config file included below for completeness:

Good news, now it registers an error in the error.log file, that /ample/public/build/bundle.js is not found. It looks (to my very untrained eye) that it's being dynamically built? Not sure where it gets called from.

[mitchray]

Sorry I deleted my comment just before yours as I didn't think it was right, are you saying you tried what I suggested?

[SimonHova]

I did what you said, unfortunately there was no change to the page or the page source, but now it's reporting an error to the error log that the bundle.js file is not found; before it wasn't even reporting an error.

[mitchray]

Ah ok, I'm leaning towards it being an nginx issue as it works on a test machine with localhost:8888/ampache/ample

Otherwise, are you using one of the pre-built Ample releases? Its built with Svelte which requires compiling, so if you're just using the raw git repo that could be why

[SimonHova]

Yes! The problem was indeed that I was cloning directly from git, the pre-built release works brilliantly. Sorry, I should have read the installation directions closer. Looking forward to digging into this now!
