Dependencies not available anymore on repo.typesafe.com (play 2.5.6)

Play Framework

Hello,
I have a problem building an old play 2.5.6 application. It was building correctly 2 months ago, but now the dependencies are not available anymore.
Why were the dependencies removed?
How can I make the build work?
Upgrade is not possible.

Thank you very much for your answers,
ido

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.6")

Hmm, those are pom-only artifacts, strange that it’s trying to download jars for those. I’m not sure those would ever have existed. But anyway the repo should return ‘not found’ rather than ‘connection refused’ for them. Does this still happen after switching to https?
