If your deployment server is Linux, mostly, because path is case-sensitive.

If your composer.json contains section such as below

...
"autoload": {
    "psr-4": {
        "App\\": "app"
    },
},
...

Composer PSR-4 autoloading expect to find class

\App\Controllers\Auth\AuthController

in file

 app\Controllers\Auth\AuthController.php

but it can not find it because yours is

 app\controllers\Auth\AuthController.php

Since your development machine seems to use Windows which by default is case-insensitive,

 app\controllers\Auth\AuthController.php

equals to

 app\Controllers\Auth\AuthController.php

Which is why it works on your development machine but not on deployment server.

So the solution is to rename any directory/files to match its case and also make sure that all files is copied to deployment server.

After you change directory/filename case, run

$ composer dump-autoload

So new autoload file is generated.
