Try expo-cli start --tunnel Working for me.

 [16:13:53] Expo DevTools is running at http://localhost:19002 
 [16:14:10] Your native app is running at exp://fa-2jw.testdev.testdev-expo.exp.direct:80

If the new project build doesn't solve it,

Your uri will look like this.

Your URL is: exp://192.168.43.61:19000

as opposed to this.

exp://9h-hcy.bacon.tickle_me_elmo.exp.direct:80

Then you can try this.

exp start --tunnel and check to make sure you have a pretty solid wifi connection

If not exp start -m tunnel

A detailed description of the connection.

I've had the same problem and no answer here helped me. In fact, I've had a older version of Expo on my iPhone. So, I've update to the latest expo version in my iPhone and then it worked perfectly.

I updated both Node.js on the computer and Expo App on mobile to the latest version. then it worked for me.

Had the same issue.
I am using PC, compile my project through expo and testing on Iphone.
This worked for me.

yarn ios

When i used yarn start, I got the same error message as you.

After spending a couple of hours and trying various the below trick worked for me My node version was updated to 13.0. I downgraded by following below commands

$ npm install -g n
$ n 12.14.1

and reinstalled expo cli again expo version is 3.24.2. (you can check version by expo -- version)

• created new project by command expo init (projectName)
• npm start
• once metro bundler
• toggle LAN to toggle and then set back to LAN as shown in picture

Make sure you switch from the LAN toggle to the Tunnel toggle in youre browser Localhost after running expo start in terminal. also make sure your internet is stable.

I had the same issue. The problem was that my computer was connected to another Wifi than my iPhone.

So to make this work, both devices have to be in the same network.

I hope that helps.
