React Native Expo应用中Axios无法发送本地HTTP请求排查

我正在开发React Native Expo应用，对接运行稳定的.NET后端。此前移动端通过Axios发起的本地HTTP GET请求完全正常，请求在useEffect中调用，代码如下：

useEffect(() => {
    async function getAll() {
        const response = await axios({
            method: 'GET',
            url: `${baseUrl}/ItemName`,
            headers: {
                authorization: `Bearer ${authToken}`,
                'content-type': 'application/x-www-form-urlencoded'
            }
        }).catch(err => console.log(err));

        if(response?.data) {
            setItemName(response.data);
        }
    }

    getAll();
}, []);

为了替代后端Swagger手动复制令牌的方式，我新增了注册页面，表单功能正常，但添加POST注册请求后，所有请求（包括之前正常的GET）均失效，返回Axios超时错误，且后端未收到任何请求（后端控制器日志仅在Postman/Swagger请求时触发）。POST请求代码如下：

const postNewUser = async (values) => {
    try {
        const postObject = {
            method: 'POST',
            url: `${baseUrl}/User/Register`,
            data: {
                firstName: values.firstName,
                lastName: values.lastName,
                username: values.username,
                password: values.password,
                email: values.email,
                phoneNumber: values.phone,
                birthDate: moment(values.birthDate).toISOString()
            },
            headers: {
                'content-type': 'application/json'
            }
        };

        const response = await axios(postObject);

        if(response) {
            navigation.navigate('Login', {
                desiredUsername: values.username
            });
        }
    } catch(err) {
        console.log('Error: ', err);
    }
}

已进行的排查操作：

• 更新Node.js至最新版本
• 更换多个不同版本的Axios
• 尝试使用不同的baseUrl：localhost、10.0.2.2、本地IPv4地址
• 测试发现localhost和本地IP请求返回较快，10.0.2.2请求需等待30秒，但所有请求最终均返回相同的超时错误

当前仅在移动端Expo应用中测试，Web版因SecureStore无法使用未测试，添加注册请求前移动端GET请求完全正常。
