Android Unit tests started failing suddenly

All of my unit tests on Bitrise started failing today. They were working yesterday on Bitrise and still runs just fine on local machine.

On bitrise, it fails with following error:

java.lang.AssertionError at MavenArtifactFetcher.java:115
        Caused by: java.util.concurrent.ExecutionException at AbstractFuture.java:588
            Caused by: java.net.SocketException at Net.java:-2
