nginx doubling the full domain when linking image assets in Laravel project

I've got a webserver running a Laravel (Statamic) website served with nginx. There is a CMS portion of this site that uses local storage to serve up images from the project folder. However, when the browser tries to pull those images, it fails (404 errors) for the assets only.

The request tab in my chrome dev console is showing that the URL for this asset is wrong. When I actually hit my server, the url looks like staging.site.com/staging.site.com/storage/images/image.png. I checked the URL in the HTML itself and it does not match that pattern, instead it looks like staging.site.com/storage/images/image.png (as expected). For some reason that I don't understand, it seems to be doubling the subdomain, domain, and TLD once it hits nginx (I think?).

Stuff I've Checked

• Laravel's symbolic links are set; I've double checked by running php artisan storage:link, which confirmed it had already been run. The images are on the server, I can see them in the terminal when I SSH in and cd into the correct folder
• If I manually remove the first domain chunk it renders the image, so the image is accessible on the server, it's just setting the URL wrong.
• I checked my nginx and laravel logs on my server and I'm not seeing any error messages in either of them that look even remotely relevant

Extra info

• I used certbot for SSL
• Everything works as-expected in local development environments. The fact that this issue is only present on the server leads me to believe it's an nginx configuration issue
• I don't think this is a ufw issue because I can access the file fine as long as the URL is correct

What in the world is going on here? Why is my domain getting duplicated?
