'Unable to connect Android phone to my project with Expo

I created my project in react native by CLI:

_npm install -g create-react-native-app
_create-react-native-app AwesomeProject
_cd AwesomeProject
_npm start

Then I installed expo in my Android phone, and scanned a QR code on my computer screen.

However, my phone can't connect to project, and I don't know why. It just loads and fails. This is error message:

Could not load exp:// 192.168.56.1:19000. Network response timed out.

This is view error:

"Uncaught Error: java,not.SocketTimeoutException: faild to connect to/192.168.56.1 (port 19000) after 10000 ms.

I'm trying to fix it, but still can't get it working. My phone and my laptop are on the same network. What can I do now?

react-native expo

I had the same problem but solved by running expo start --tunnel

Solution 2:^[2]

Select LOCAL instead of LAN.

I kicked myself when I fixed this.

Solution 3:^[3]

Choose Tunnel Instead of LAN or Local in connection tab. This solved the issue for me.

I had the same issue, turns out my firewall was blocking my connection to the development server port (for me it was 19000). Solved it by disabling firewall.

Keep a look on this issue for the answer: https://github.com/react-community/create-react-native-app/issues/60

Solution 6:^[6]

Make sure that your device and computer are one same LAN/Wifi. It will work. Also use LAN option.

Solution 7:^[7]

check open port using

ufw status verbose

And if you don't see the port You are working on for example 19000 => expo try this

ufw allow 19000

I've had a similar problem on iOS - the project showed up in the Expo app but didn't want to connect.

Here's what I did:

Connect your PC to your device through USB cable
Download the newest xde from: https://github.com/expo/xde/releases
Install XDE, create a new project from the gui (do NOT use your old project from create-react-app, as it may also show up in XDE) and click the newly created (in XDE) project under "My Projects".

Now your project should show up in the Expo app on your phone. If it doesn't try sending yourself the link to your app over email (to your own inbox, and open the link on your phone), mine looks like this: exp://5c-gp9.[accountname].my-new-project.exp.direct:80

I had this problem when my phone was connected via wifi and my destop was connected via LAN. I changed the connection mode in the browser window to tunnel, reloaded the expo app and was able to connect to my application. This was on my iOS device.

I got this issue on Win 10 with android and solved by the adding a firewall rule for my device (device IP as remote). I was using ESET NOD antivirus and it was block the device from accessing node.exe

Solution 11:^[11]

for local testing e.g comnputer , simulator

expo start

for Real mobile device

expo start --tunnel

Solution 12:^[12]

I was having the same issue, the solution is easy just make a Firewall rule that allows connection from your mobile device to your PC. open port number 19000 and in the IP put your phone IP address then allow the connection TCP/UDP in both directions, and everything will be OK. Usually, you can edit the Firewall rules through your antivirus installed on your PC.

Careful don't disable your firewall, it will hurt you a lot.

Solution 13:^[13]

This problem is due to the sdk version of the project is not compatible with the expo go ,so go to app.json of your project and edit to the latest version of sdk

Solution 14:^[14]

I'm on windows 10.

My network was set to public, but it needed to be private - so that it could safely expose devices like printers and in this case the Expo connection.

I went in my Wifi setting and clicked on Private:
