error connect ECONNREFUSED websocket

Im trying to build p2p server in node.js using ws package but after running $HTTP_PORT=3002 P2P_PORT=5002 PEERS=ws://localhost:5004 npm run dev i get an error :Listening on p2p port 5002 Listening on port 3002 events.js:165 throw er; // Unhandled 'error' event ^ Error: connect ECONNREFUSED 127.0.0.1:5004 at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1174:14) Emitted 'error' event at: at WebSocket.finalize (/home/ris/Desktop/gj- chain/node_modules/ws/lib/websocket.js:190:41) at ClientRequest._req.on (/home/ris/Desktop/gj- chain/node_modules/ws/lib/websocket.js:639:10) at ClientRequest.emit (events.js:180:13) at Socket.socketErrorListener (_http_client.js:395:9) at Socket.emit (events.js:180:13) at emitErrorNT (internal/streams/destroy.js:64:8) at process._tickCallback (internal/process/next_tick.js:178:19) [nodemon] app crashed - waiting for file changes before starting... I tried reinstalling dependencies,change ports, kill processes on all ports(3002,5002,5004) but it didnt work. I believe there is some dependancy mess, im using ubuntu 16.04 node 9.11 / npm 5.6.0 version.
