Start React Native : Error 502 from maven-metadata.xml-CodePudding

When I execute npx react-native run-android I have a 502 error that does not allow me to start my project.

I have read these recents topics : "React Native: Android "Received status code 502 from server: Bad Gateway" from JCenter and Bintray being discontinued" et "Could not HEAD maven-metadata.xml. Received status code 502 from server: Bad Gateway".

They mention that the breakdown is repaired. It's confirmed on the official website : Sporadic 502 Bad Gateway, 500 Internal Server Error for maven-metadata.xml resources

Sometimes I read that it can come from my cache. How to check this?

Try this, go to the android folder, and in build.gradle file change every "jcenter()" into "mavenCentral()".
