错误:应用程序中的网络错误使用axios进行本机反应

我看到有很多相关的问题，但没有一个能解决我的问题。

我的包.json

"axios": "0.18.0",
"react": "16.9.0",
"react-native": "0.61.5",

我的api请求

import Axios from "axios";
const SERVER = Axios.create({
baseURL: 'https://***.***.com.br'
});
export default SERVER;

和我的actionReducer

export const register_user = ({ name, email, password, password_confirmation }) => {
return dispatch => {
dispatch(
{
type: CREATE_USER
}
)
let url = "/users"
Axios.post(`${SERVER}${url}`, {
"user": {
"name": name,
"email": email,
"password": password,
"password_confirmation": password_confirmation
}
})
.then(() => {
Alert.alert('Registrado com sucesso!')
registerUserSuccess(dispatch)
})
.catch((err) => {
registerUserError(err, dispatch)
})
}
}

错误正在下降，控制台上出现以下错误：
