I get an error when I wanna run my expo app on metro bundler. This is the error:

"Uncaught Error. java.net.SocketTimeoutException. failed to connect to exp.host/104.197.216.164(port 443) from (port () after 10000ms"

I tried different ways. upgrading expo-cli, downgrading expo-cli, disabling firewall, disabling Antivirus. didn't solve the problem Can anyone help? thanks in advance

I had the same error, what worked for me is to ensure that my computer is connected to the same Wi-Fi network as my device and that in the network settings on the pc they are in a private network, using these 2 things worked perfectly for me. I hope to see you helped, postscript I do not speak English I hope you can understand me

Connect with USB, turn on USB Tethering and enable developers mode on your android mobile.

    Adding to this to make it work, I entered into the Expo the manual url exp://127.0.0.1: - so localhost - in my case: exp://127.0.0.1:19000 – gabore Jan 17 '23 at 08:14
  • `expo start --localhost` then in your mobile device click on manual url and enter the exp link shown in console like `exp://127.0.0.1:19000` – NineCattoRules Mar 31 '23 at 11:54

I was getting the same error, my app would not load. So I changed the network from public to private in 'Windows' and it worked !!!

none of these things worked for me until I changed the exp://IPGoesHere:1234 to the ip that is shown from my phone wi-fi network

Verify that the PC and the cell phone are in the same Wi-Fi network, it happened to me that I did not have Wi-Fi and was connected from my cell phone with data and the PC with Wi-Fi, I put the Wi-Fi on the cell phone and it worked, it is an option, try .

If you are under WSL2 then you have to run npm start using native windows npm. They have different IPs.

The solution is very simple: Go, Setting > Network & Internet > Wi-Fi > click on connected Wi-Fi and simply change public network into private network.
