Description

Hi!
I'm having problems to perform any http request using axios to a local server:
axios.post(url, data)

and for url I tried:
url = "http://localhost:3000/authenticate"
url = "http://127.0.0.1:3000/authenticate"
url = "http://192.168.1.10:3000/authenticate" //server ip address
url = "http://10.0.2.2:3000/authenticate" //emulator address

and NONE of them worked...

The funny thing (and I can't understand why) is that as soon as "Debug JS Remotely" the following url worked perfectly:
url = "http://10.0.2.2:3000/authenticate"

So, how should it be my set up to make this work without debugging js remotely??

Reproducible Demo

export const loginUser = userData => {
  return dispatch => {
    axios
      .post(`${url}/authenticate`, userData)
      .then(res => {
        if (res.data.success) {
          dispatch(setUser(res.data.user));
        } else {
          //Auth error
          dispatch({
            type: SET_ERROR,
            payload: res.msg
          });
        }
      })
      .catch(err => console.log(err));
  };
};

I have the same issue on my project while using the 16.7.0-alpha.2 version of React. @fedecryto did you manage to solve the problem?

Hi @Cytren, I managed to solve it, but unfortunately was unintended. As soon as I cleared up a couple of warnings I had, the issue was magically gone. I couldn't find a way to reproduce the problem again.... and the warnings I cleared were independent of axios... so no clue what happened there. Probably one of those warnings was messing up other things... Sorry but I don't have a clear answer for you :s
