404 error is displayed at httprequest.

I’m ionic v4 with https://blog.fliche.net/ionic-4-user-registration-login-tutorial/ and https://blog.fliche.net/laravel-rest-api-passport-authentication-for- I am trying to create a login function referring to ionic-app /.

When debugging with google chrome, “POST http://mydomain.com/laravel-auth-passport/auth/register 404 (Not Found)” is displayed and I can not send the text entered in the form.

I am Japanese, so I can not speak English very much, but would you give me some advice?
