Expo Development Build on Simulator Network connection lost

Question

I built development builds for an Expo an and as soon as I did that, I was not able to to connect to the expo development server from the iOs simulator. I tried:

downgrading expo, react-native
resetting router
opening ports on the router
running a completely new, 'naked' expo app and installing dev builds

Nothing works. Same with android and the emulator. And an iPhone.

On iOs I receive the error: Failed to load app from http://...... The network connection was lost. On android I receive the error: Unexpected end of stream on http://

Does anyone have an idea what could be done to fix this?

I had the same issue and managed to solve it by downgrading from NodeJS 20 to NodeJS 18 (the LTS). If you're on NodeJS version 20, you might wanna try to downgrade.

The same. If you are using Brew you could do: brew install node@18 && brew unlink node && brew link --overwrite node@18 – guyromb May 25 '23 at 17:24
