Can not test after publishing using Expo xdk

I am trying to test the “publishing” in expo xdk under linux. It was working normally when I had the xdk opened.
And then I closed the xdk , the project on expo app shows me the error “Tunnel packager.blablabla” not found

I suppose I don’t need to keep anything open if I have “published” the project? Please correct me if I have some mis understanding

Hi, if publishing succeeded, then your app should be accessible with a published url like instead of the tunnel url.

If you’re having issues with the tunnel provider during development, you can try restarting your project (which will also try to reestablish the tunnel), or you can switch to localhost/LAN.
