Laravel returning IP address for assets instead of domain

I'm trying to set up a local Laravel Homestead (5.3) environment for my API. I want to be able to hit the API locally through my Android app.

I've set everything up, including getting the Android app to trust the server's certificate, but now I'm getting the following issue:

The app trusts my server's domain (in my case, homestead.test). The problem is, my server is returning all assets with the IP address of the server, which is 192.168.10.10, so all assets return in the form of:

https://192.168.10.10/storage/img/posts/6/thumbnails/1.jpeg

For whatever reason, the Android app doesn't trust this IP as I guess I don't have the certificate for it set up. Instead, I need it to return with the domain, homestead.test, so it looks like:

https://homestead.test/storage/img/posts/6/thumbnails/1.jpeg

In my hosts file (Windows), I have this already:

192.168.10.10  homestead.test

How can I make this change? I've tried changing APP_URL to https://homestead.test in the .env file, but that doesn't seem to have changed anything.

What am I missing?
