Hey everyone, I’ve been having this issue for quite a long time now, I’ve seen a lot of people asking for the same problem here, tried everything but still doesn’t work.

I’ve tried uninstalling node, expo-cli, deleting .expo, closing all local ports, but it just keeps showing this error. Here’s the full log of the erro:
ps. I’m using Mac and I used to have flutter installed, don’t know if that can cause any possible errors.

Does anyone know how to solve this??

Hey @lucasheise,

Can you run expo diagnostics and paste what’s printed out here? Also, has the expo-cli worked before for you on this machine or has it yet to?

Cheers,
Adam

Hey @adamjnav, thanks for the reply, expo-cli has worked normally before (and it worked for quite a while) and suddenly started doing this.

ps. I forgot to mention that I’ve also tried to delete all my node_modules and run npm install, but didn’t work as well .

Here’s my expo diagnostics:

Thanks in advance

@adamjnav any news??

I encounter this econnrefused issue as well.
For me it doesnt help to remove the .expo folder.

Im not sure if it is the same for you as for me.
When I publish my package i get this error, when I publish again straight after, I do not get the error and can successfully publish the package.
Each time u run the code, the first publish will fail with econnrefused but after that it succeeds.

Would still love to fix this but as long as it works on second try I can manage. I didnt have this error at first and now I do get it with every pc i try and also with packages after a basic expo init.

Hey @xuthal, thanks for the reply, I’ve never actually published a expo project. When you say publish, you mean that you can run expo publish to run on an emulator? I usually just run expo start to run the emulator

Oh @xuthal, I got it working by running expo publish, deleting the project on expo.io and then running expo start. Not sure why this happened tho…
