EADDRINUSE :::4000 means that you have some other server running on port 4000. Close any conflicting programs, or change the port that tansa uses here: https://github.com/dennisss/tansa/blob/master/src/server/node/index.js#L24 and https://github.com/dennisss/tansa/blob/master/src/core/messaging.cpp#L25 .
