Network Request failed - React Native - android

Question

the below is my Fetch code:

return fetch('https://172.16.57.200:8080/cebip/financeProductList',{
        method: 'GET',
        headers: {
          'Accept': 'application/json',
          'Content-Type': 'application/json',
        }
      })
        .then((response) => response.json())
        .then((responseJson) => {
          alert("hi");
          console.log(responseJson);
        })
        .catch((error) => {
          alert("error");
          console.error(error);
        });

and i get the below error in android :

I changed the port of my own server to 19001 and it worked for me. If you are developing your own server maybe you should try this way. I hope it worked to you
