This is, in my experience, an issue not relating to your code, but the settings on your phone or the network itself.根据我的经验，这与您的代码无关，而是与您的手机或网络本身的设置有关。
Here's a few steps I recommend:以下是我推荐的几个步骤：
- Make sure wireless debugging is turned on.确保无线调试已打开。 My OnePlus phone often turns off wireless debugging when I switch networks.我的一加手机经常在切换网络时关闭无线调试。
- Switch to tunnel, there are often funny issues on Public Networks.切换到隧道，公共网络上经常有有趣的问题。
- Go to settings on your phone and find expo's settings. Go 到手机上的设置并找到 expo 的设置。 Turn the setting "Display over other apps", to off then on again (it should definitely be on).将“显示在其他应用程序上”设置关闭然后再次打开（它肯定应该打开）。
- Uninstall Expo Dev clients AND builds, this is often the cause for me.卸载 Expo 开发客户端和构建，这通常是我的原因。
- Try a wired connection (make sure USB debugging is on).尝试有线连接（确保 USB 调试已打开）。
- Reinstall Expo Go on your phone在手机上重新安装 Expo Go
This can be a real pain, good luck to all.这可能是一个真正的痛苦，祝大家好运。

Restarting the terminal where you're running Expo is what worked on my end:)重新启动您正在运行 Expo 的终端对我来说是有效的:)
