react-native: The development server returned response error code:404

I see the same red screen. Is some new update the cause of this error? In the terminal i get

::ffff:127.0.0.1 - - [15/May/2018:12:50:43 +0000] "GET /index.android.delta?platform=android&dev=true&minify=false HTTP/1.1" 404 79 "-" "okhttp/3.6.0"

Did you solve this?

@maximten ,thanks, it worked for me. https://stackoverflow.com/questions/50344830/react-native-cannot-read-index-android-delta

I had same error. In my case I did: run in cmd : react-native start if it’s complain that can’t listen on some port (in my case it was 8081), kill all processes on this port: on linux: fuser -k 8081/tcp then run react-native start

Have the same problem too

Thank you all for the help! I added compile ("com.facebook.react:react-native:0.55.4") { force = true } to app app/build.gradle and I had to update react-native: yarn add react-native

Now I get a new error from RNFS that is probably not properly linked but that’s another story 😃

Seems like something changed on FB’s side.

I changed the following to make my project work again. This forces the correct version:

1. build.gradle (note that resolutionStrategy is only available from a certain gradle version onwards. I’m on 3.1.0)

allprojects {
    ...
    repositories {
        configurations.all {
            resolutionStrategy.eachDependency { DependencyResolveDetails details ->
                def requested = details.requested
                if (requested.group == 'com.facebook.react' && requested.name == 'react-native') {
                  details.useVersion '0.44.3'
                }
            }
        }
    }
}

1. app/build.gradle Change this

compile "com.facebook.react:react-native:+"

to

compile ("com.facebook.react:react-native:0.44.3") {
    force = true;
}

It looks like the problem is faced by lot of now from yesterday onwards. I can see this error says server is trying to connect to 10.0.2.2:8081 Not sure why server is trying to connect to this address instead of localhost.

I have same problem
