cql-io-tests: Network.Socket.connect: <socket: 11>: does not exist (Connection refused)

This might be a system configuration issue on the Stackage Build server.

cql-io-tests: Network.Socket.connect: <socket: 11>: does not exist (Connection refused)

But just checking - I think previously the cql-io tests worked in Stackage?
