react-native: Fetch not working in release APK

🐛 Bug Report

I use a login in my app, when I test on development environment on my phone I have any trouble I can log in. But when I build the release APK it seems like the app can not connect with the fetch (the code enter in the catch of the fetch) My AndroidMainfest.xml has the INTERNET pemission

Code Example

fetch(config.urlServer + "/index.php/AppServer/signin", { method: 'POST', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', }, body: JSON.stringify({ email: this.state.email, password: this.state.password }) }).then(res => res.json()) .then((responseJson) => { console.log(responseJson); if(responseJson.result){ this.props.setSession(responseJson.user); this.props.navigation.navigate('Main'); }else{ Toast.show({ text: responseJson.error, buttonText: 'Cerrar', type: "danger" }); } }).catch((error) => { console.error(error); Toast.show({ text: 'Hubo un Error', buttonText: 'Cerrar', type: "danger" }); })
