Adding a base-url gives 404

[Skolmeister]

Hi all,

I used glance just in my home network for a while but I want to expose it to a subfolder under https://mydomain.de/glance now.

I'm using swag as my reverse proxy and have a working setups for subfolders, which I wanted to apply to glance. The problem is, adding any base-url (base-url: /glance in this case) to the glance.yml gives me 404. Even when going directly to the page in my home network, the page is plain HTML and looks like this:

When looking at the network tab, it seems that nothing except index.html can be loaded:

As soon as I remove the base-url, the local page is working again.

Hope you can help me, I'm out of ideas where to look next.

Many thanks
