Weird errors after updating to Android Studio 3.1

Question

So I saw a new update for Android Studio and I updated.

Although I keep getting errors that are more related to server problems than anything else. But this doesn't relate to my app.

One my apps has this error Could not HEAD 'https://jcenter.bintray.com/com/sun/xml/bind/mvn/jaxb-parent/2.2.11/jaxb-parent-2.2.11.pom'. Received status code 504 from server: Gateway Time-out Enable Gradle 'offline mode' and sync project

I tried the offline part but it didn't work.

And another one has this problem

    Could not HEAD 'https://jcenter.bintray.com/com/squareup/javawriter/2.5.0/javawriter-2.5.0.jar'. Received status code 504 from server: Gateway Time-out
Enable Gradle 'offline mode' and sync project

I would appreciate any help as I am kind of last thanks

EDIT Apparently it was a problem on the gradle, although here it is

    apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

    })
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

apply plugin: 'com.google.gms.google-services'

Although now I have this error when I run my app (or try to) "09:54 Error running 'app': Unknown error"

Answer 1

I have the same issue after updating to 3.1. But it seems a temporary problem as I try to go to the 502 URL with my browser and I can load it. After trying to sync again my project, the 502 URL is a new one. Maybe too many people are updating, causing load problems.

EDIT: three hours later, it is all fine for me. Without rolling back anything. Temporary problem confirmed :)
