laravel react native axios post - react-native

Question

i have a react native app as the front end and am trying to implement login, on localhost i can login well but in production i get the error the GET method is not supported on this route supported methods POST. When i test the endpoint using thunder client from VS code it works but in my react native app i get the route not supported error.
react native code:
export const loginuser = (username,password) =>{
return async(dispatch)=>{
dispatch({type:REG_LOADER})
const headers = {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
axios.post(ROOT_URL+"login/saler", {
username:username,
password:password,
},{headers:headers})
.then( async(response) => {
console.log(response.data)
dispatch({type:LOGIN_FAIL})
let user = response.data.customer
let status = response.data.status
if(status === "1"){
await AsyncStorage.setItem('userdata', JSON.stringify(user))
dispatch({type:LOGIN_SUCCESS,payload:user})
}else{
alert('Wrong phone number or password')
dispatch({type:LOGIN_FAIL})
}
})
.catch(function (error) {
alert(error.response.data.message)
dispatch({type:LOGIN_FAIL})
})
}
}
laravel route:
Route::group(['prefix' => 'v1', 'as' => 'api.', 'namespace' => 'Api\V1\Sales'], function () {
Route::post('/login/saler','Auth\LoginController#Login');
]);
