'Bad gateway when building Android React Native

When I run react-native run-android, I get the following error:

* What went wrong:
Could not determine the dependencies of task ':react-native-intercom:generateDebugRFile'.
> Could not resolve all task dependencies for configuration ':react-native-intercom:debugRuntimeClasspath'.
   > Could not resolve com.facebook.react:react-native:+.

I have seen similar issues others were having and they said to check the status: https://status.bintray.com/ - but it's saying everything is operational. I also grepped my whole codebase for bintray, but there is no reference to it.

Edit: Also tried that URL in the browser and get the same 502

also:

Update It seems that bintray was "sunsetted" so I'm not expecting it to come back. I've replaced jcenter() with mavenCentral() and it seemed to help, but I still get errors like the following:

* What went wrong:

I tried to exclude yoga and others in the build file but it doesn't work. I have no idea what to do.

Solution 1:^[1]

It works now.

I reset my hours of changes to master and it works. Leaving this here for future people who have this error - don't trust the bintray status page, just wait. I read somewhere during my research that it will stay up indefinitely read only.

Solution 2:^[2]

I wouldn't recommend depending on JCenter, it has been unstable these past few weeks.

There's an official library from Intercom for React-Native now! It's using the new mavenCentral repo, and there's very little differences (that I found) between this and react-native-intercom. The methods are the same. You might want to migrate to it.

Solution 3:^[3]

I'm having this issue now that jcenter has sunset what seems like 2 months early. https://status.bintray.com/

Help to resolve this would be great. Adding mavenCentral() has not helped, upgrading gradle to v6.9 & React Native versions to 0.65.0. has not helped either.

I still get the error:

> Failed to list versions for com.facebook.react:react-native.
     > Unable to load Maven meta-data from https://google.bintray.com/flexbox-layout/com/facebook/react/react-native/maven-metadata.xml.

           > Could not GET 'https://google.bintray.com/flexbox-layout/com/facebook/react/react-native/maven-metadata.xml'. Received status code 502 from server: Bad Gateway

Solution 4:^[4]

I using new maven, it woking for me

File :

./android/build.gradle

changer to:

maven { url 'https://repo1.maven.org/maven2/' }

Solution 5:^[5]

Toggle Offline Mode Button

Swtich On Toggle Offline Mode(check the above image link!) in Gradle Window

You can open Gradle Window by clicking Gradle button in the right side bar.

Build > Clean Project and File > Invalidate Caches > (check) Clear file system cache and Local History > Invalidate and Restart
File > Sync Project with Gradle Files

It works after these things.
