[TypeError: Network request failed] either with fetch API or axios on android

[EshgheCode]

I have a problem with fetching an API on my code I use both fetch and axios but the result is same:
[type error: Network request failed]

here is my code for fetch:
useEffect(() => { fetch('https://jsonplaceholder.typicode.com/users') .then((res) => res.json()) .then((data) => { console.log(data) }) .catch((err) => console.log(err)) }, []);

I don't use an emulator because my CPU doesn't support vt-x. so I use a Xperia TX which has android 4.3 and I connect it over Wi-Fi to see my result. it work properly so far but the only problem is this API fetching.

React Native version:

0.63.2

I saw your issue. and I try to use my code on snack, and it worked properly :

I just wonder why it doesn't work on a real device.
isn't that because of my Android version which is quite old?

Related. Try adding headers and see if that fixes?

Try this maybe? I had a similar error, had connection but all fetch and axios calls returned an error (and sometimes straight crash depending on the endpoint) but the linked solution worked for me.

Hi @SohaibKtb @akeuk The issue got resolved for me after correctly installing the SSL Certificate.

@gvsakhil , can u please let me know the steps to install SSL certificate in Android & iOS?

Hi @SohaibKtb @akeuk The issue got resolved for me after correctly installing the SSL Certificate.

how? i have same problems

Same issue here, but the TLS certificates are correctly installed:

• chrome shows a valid chain accessing the same webapi
• other apps doing the same request are successful

The TypeError: Network request failed is a generic and useless error used for tons of reasons.
The most probable solution is here: #32931

In any case, throwing a generic error is a bug without any doubt. And it should be fixed.

fetch("https://jsonplaceholder.typicode.com/todos/1") request sometimes hangs for 2 minutes, cannot find any solution

The fetch API is asynchronous.
If it is blocking, it depends on your code.
If it takes a long time (regardless your code is blocking) it depends on some wrong parameters/URL or connection issues or server side issues.

In any case the react-native api does not provide a detailed error information, which is the point of this open issue.

I created a new Expo project, added only one fetch button and tested, with iOS it works without any issue, hang is occuring on Android, when I leave the phone for 5 minutes and then call function it defenitely waits always ~2 minutes to send request and get response, I am looking for soluftion for a week but cannot find any solution,

This is not very relevant.

• You should assume that fetch works well on every platform as it is the most used API.
• If it hangs, it means you wrote code that is waiting synchronously (which is wrong)
• This is not the right place as the issue title deals with a different problem.

My suggestion:

• start with the exact code of an official tutorial
• if you feel there is something wrong, open a new issue as you (we) are OT here

with no activity.

... "with no fix" would better represent the general problem
