Hi

What does expo diagnostics give you? Post it here like this:

```
diagnostics here
```

Also, do you have the same SDK version in app.json and package.json?

Does expo start work for you after upgrading to SDK 34?

@tigpalmas2 you need to run expo start before running expo build:android :+1:

Thanks Charlie.

This is new. So now we have to run expo start and then expo publish in another terminal.

No, sorry, you should run expo start at some point before building your binaries. You don’t have to keep it running during the build

Thanks for clarifying. I had the same ECONNREFUSED message when running expo publish. I had to run expo start in one terminal and then expo publish in another. No error message. My case could be isolated.

I haven’t tried expo build yet but will later.
