I'm getting the same error, but only from Android. I don't think this is related to Axios because I used the bare JavaScript fetch method and the API call just never resolves.

I'm stuck at this problem for like 1 week. Some people say that axios isn't using an API that called NSURLSession provide by Apple to make a request so when user switch to another app the OS just cancel that request.

Honestly, in my case, I'm convinced that this is a backend problem. I created a basic Node.js backend and made a similar API call to it; everything was working just fine. We are looking into the issue and will keep you updated if we figure this out.

@nkqdev If it's GET data, if fetch data error, it should have chance to retry few times. check this article 3 Tips to Make Your App More Stable

@kurucaner And the android error, I think it's because you use '127.0.0.1' or 'localhost', I met this error before, and change the local IP to LAN ip(for example, like 192.168.1.10), then it's worked.

I use expo and this is how I get LAN ip in dev mode:

import Constants from 'expo-constants';

const host = Constants.expoGoConfig?.debuggerHost?.split(':')?.[0];
const API_URL = process.env.EXPO_PUBLIC_API_URL || '';

export const baseURL =
  host &&
  (host.startsWith('192.168') || host.startsWith('10.') || host.startsWith('172.')) &&
  (API_URL.indexOf('localhost') > -1 || API_URL.indexOf('127.0.0.1') > -1)
    ? 'http://' + host + ':' + (API_URL.split(':').pop() || '')
    : API_URL;

@suhaotian I'm using SOAP service so when it's say Network Error everything just stop and i don't see any retry

Guys I found solution. Its not axios problem. You need add certificates into your network_security_config

Also add android:usesCleartextTraffic="true"

Also add xml folder into your res/ and paste this code:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="@raw/ca" />
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

After that you need add your certificates into res/raw/NAME_OF_CERT

That's all!

Get an ssl certificate from aws. I think it's free of cost
