Research direction

Start by reproducing the OpenShift Docker setup and inspect the compatibility failure reported from /usr/src/server.js, along with the socketcluster-server stack entries. Compare the SCC component and scc-state versions involved, then verify that the server accepts the client handshake without CompatibilityError or SocketProtocolError.
