Routing in Yii2 throws out 404-error - yii2

Question

following routing-rules work fine under WINDOWS/XAMPP(Apache), but it fails under LINUX(nginx) by throwing out 404-Error.What are differences in defining rules in yii2 as regards these two Operation Systems?
'urlManager' => [
'class' => 'yii\web\UrlManager',
'enablePrettyUrl' => true,
'showScriptName' => true,
'enableStrictParsing' => true,
'rules' => [
'/' => 'site/login',
'reset'=>'site/request-password-reset',
'about' => 'site/index',
'contact' => 'site/contact',
'logout' => 'site/logout',
'signup' => 'site/signup',
'formular' => 'site/script',
'praktikum' => 'bewerbungen/index',
'<controller:\w+>/<id:\d+>' => '<controller>/view',
'<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
'country' => 'country/index'
],
],

Here is first Nginx-config-file,as deliberated:
