No downloads from Docker image on Server

[BlackF0rest]

Question

Hey,
I am developing a small Inventory management system for a parts storage. I have it running as a Docker on a gitlab-ci server. Port 80 is set open for the server and I can access the server from my laptop, but I can't seem to use the download feature I implemented. When I run the Code locally on my laptop it works fine, but on the server I get nothing. Has someone an idea where the error lies? Does Nicegui need any more ports for download, or do I need to be aware of some restrictions? Or could it be a browser error?

Just to have it complete this is the code i use to download a zip folder of images but as the code works locally i dont see why the rest of the code is important :)

ui.download(shutil.make_archive('labels', 'zip', 'download_temp'))

Hi @BlackF0rest,

It sounds like there is no websocket connection after loading the page. To verify, try a simple button to show a notification:

ui.button('Hi!', on_click=lambda: ui.notify('Ho!'))

Or maybe shutil.make_archive fails? What do you see in the log on the server? And what in the browser console?
