I read the [document on OAuth2 authorization](https://developer.mautic.org/#oauth-2) and went to [http://my.mautic.base/oauth/v2/authorize?client\_id=my\_client\_id&grant\_type=authorization\_code&redirect\_uri=http%3A%2F%2F127.0.0.1%2Fcallback%2Ffor%2Foauth2&response\_type=code&state=yddtxdmq](http://my.mautic.base/oauth/v2/authorize?client_id=my_client_id&grant_type=authorization_code&redirect_uri=http%3A%2F%2F127.0.0.1%2Fcallback%2Ffor%2Foauth2&response_type=code&state=yddtxdmq) via Chrome to get an authorization code. I was prompted to login there, and I got Not Found error after logging in. In my API credentials, the callback URI is [http://127.0.0.1/callback/for/oauth2](http://127.0.0.1/callback/for/oauth2). Why I cannot get an authorization code? ---
