const fetching = () => {
            fetch('http://SERVER_URL/get', {
                method: 'GET'
             })
            .then((res1) => {
                fetch('http://SERVER_URL/post', {
                    method: 'POST',
                    body: JSON.stringify({ params: [
                        'element1',
                        'element2',
                        'element3',
                        'element4'
                    ] }) }
                )
                    .then((res2) => {
                        console.log('OK');
                    })
                    .catch((err2) => console.log('NOT OK')); 
            });
            
        };

        setInterval(fetching, 10);

Same issue!

I'm sure this issue is related exclusively to RN because I have two exact copies of the same app, on running on RN 0.33 and the other one running on RN 0.39 and second app keeps failing network requests.

@max-mykhailenko @juldiadia Maybe it's not related, but this fixed it for me #11342
