Running label studio on https with nginx; error when connecting local storage

Label Studio Support
1

I use Label Studio on a server. To serve label studio on https I use nginx. The server has a hard drive on which the data is stored. The connection with local storage has worked, but I get the following error when I try to load the images in the labeling interface

image
image965×291 23.3 KB

The image does not appear to be available at https://ip_adress/data/local-files/?d=Image_Storage/compressed_image_12_2025-01-22.png, but when I manually change the URL to https://ip_adress/data/local-files/compressed_image_12_2025-01-22.png, the image loads.

How do I get the image to load correctly in my labeling interface?

version of Label Studio
Label Studio version: 1.16.0 installed by pip

labeling configuration.
