Could not resolve org.webkit:android-jsc:+. when building and installing for android


I am getting this error “Could not resolve org.webkit:android-jsc:+.” when trying to run “npm run android” this morning. It was working on Friday. Full detail below:

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Could not resolve org.webkit:android-jsc:+.
     Required by:

         > Unable to load Maven meta-data from
            > Could not HEAD ''.
               > Read timed out

I started a new project from scratch using npx react-native init AwesomeProject it failed with same error.

I have another project on older version of RN at 0.63.2, which can build as expected. These ones which are having issues are on 0.63.4 and 0.64.0

Seems like remote artifact repo is down to me..
