Yii2 pretty urls returning 404 - php

Question

I am using nginx and yii2 trying to create a little sample crud rest API, and whenever I enable pretty urls I can't access my routes anmymore.
My config is as follows :
'urlManager' => [
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
'rules' => [
[
'class' => 'yii\rest\UrlRule',
'controller' => 'user',
'only' => ['delete', 'create', 'update', 'get'],
'patterns' => [
'PUT users/<id:\d+>' => 'user/update',
'DELETE users/<id:\d+>' => 'user/delete',
'GET users/<id:\d+>' => 'user/get',
'POST users' => 'user/create',
]
],
[
'class' => 'yii\rest\UrlRule',
'controller' => 'campaign',
'only' => ['delete', 'create', 'update', 'get'],
'patterns' => [
'PUT campaigns/<id:\d+>' => 'campaign/update',
'DELETE campaigns/<id:\d+>' => 'campaign/delete',
'GET campaigns/<id:\d+>' => 'campaign/get',
'POST campaigns' => 'campaign/create',
]
],
],
],
Note that when enabling this, I can access gii without any issue at /gii instead of /index.php?r=gii
When disabled, my routes work fine using index parameters. Also it's yii giving me 404 and not directly nginx.
EDIT: This url works /user/get?id=1
However this one does not /users/get/1, nor /user/get/1
A POST on /users will work, but not any of the other http requests
