i am getting a same error When i try to connect my node.js server in a react-native expo app. My SSL is working correctly on Postman but native is giving an error. Do you know how can i solve this?

My Native Code:

const serverUrl = "https://israbilisim.com/api/user/login";

const calistir = async () => {try {const response = await axios.post(serverUrl,{username: user,},{headers: {"Content-Type": "application/json",},});

catch (error) {console.error("İstekte bir hata oluştu:", error.code);if (error.response) {console.error("Sunucu Hatası:", error.response.data);console.error("Durum Kodu:", error.response.status);alert("Sunucu Hatası: " + error.response.data);else if (error.request) {console.error("Yanıt Alınamadı:", error.request);alert("Sunucuya ulaşılamadı, lütfen bağlantınızı kontrol edin.");else {console.error("Hata:", error.message);alert("Beklenmeyen bir hata oluştu: " + error.message);}}

};

Native Error Message:
