The GET method is not supported for this route api.php

I'm trying to make APIs using laravel. They are working fine on localhost but when I upload them to my server they give me error

405 Method Not Allowed

routes/api.php

<?php

use Illuminate\Http\Request;

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

Route::post('logout', 'API\LoginController@logout');

Route::resource('users', 'API\UserAPIController');

Controllers\API\LoginController.php

<?php

namespace App\Http\Controllers\API;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\User;
use App\Http\Controllers\API\APIBaseController as APIBaseController;
use DB;
use Validator;
use Hash;

class LoginController extends APIBaseController
{

    public function logout(Request $request)
    {
        $user = User::find($user_id);
        if (is_null($user)) {
            return $this->sendError('User not found.');
        }
        User::where('id', $user->id)
        ->update([
            'imei_no'=>'',
            'device_id'=>''

        ]);
        return $this->sendResponseArray($user_id, 'User successfully logout.');
    }
}
