Laravel routes not working when installed in a subfolder - php

Question

I need help running Laravel from a subfolder in our dev environment.
Our devs have to clone the main site repo into a folder under their subdomain like so:
https://developer.example.com/branch/ points to /var/www/html/developer/branch/
Examples:
https://dev1.example.com/laravel8/
https://dev2.example.com/ticket-12345/
https://dev3.example.com/some-other-branch/
We currently run a homegrown PHP app that this works just fine with, trying to migrate to Laravel (testing with v8.0) I'm finding all routes are broken unless they contain the subfolder name which is not feasible.
// Doesn't work
Route::get('/', function () {
return view('welcome');
});
// Works
Route::get('/laravel8', function () {
return view('welcome');
});
// Doesn't work
Route::get('/welcome', function () {
return view('welcome');
});
// Works
Route::get('/laravel8/welcome', function () {
return view('welcome');
});
// Legacy route handler (Works)
Route::any('/{path?}', LegacyController::class)->where('path', '.*');
I've tried setting the APP_URL to https://dev1.example.com/branch/ which does nothing.
Our NGINX config rewrites requests like so
https://developer.example.com/branch/ -> https://developer.example.com/branch/public/index.php
server {
server_tokens off;
listen 80;
autoindex off;
server_name dev1.example.com;
root /var/www/html/dev1;
access_log /home/dev1/nginx-access.log;
error_log /home/dev1/nginx-error.log debug;
rewrite_log on;
index index.php index.html;
client_max_body_size 100M;

}
}
Any help is appreciated.
