Could not HEAD Received status code 504 from server: Gateway Time-out

I am getting the error as the below

`Could not HEAD 'https://oss.sonatype.org:443/content/repositories/snapshots/com/github/bumptech/glide/recyclerview-integration Received status code 504 from server: Gateway Time-out`

https://github.com/bumptech/glide/blob/master/build.gradle#L69-L71

Start with build.gradle lines 69-71 and the reported HEAD request to oss.sonatype.org. Run the relevant build or dependency resolution to determine whether the 504 is reproducible; done means the issue is either documented as an external repository outage or the build configuration is updated and dependency resolution succeeds.
