composer-rest-server Error: throw er; // Unhandled 'error' event

I installed and startet my business network. Now I want to do composer-rest-server -c admin@test-network but I get the following output:

Discovering types from business network definition ...
Discovering the Returning Transactions..
Discovered types from business network definition
Generating schemas for all types in business network definition ...

      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE :::3000
    at Server.setupListenHandle [as _listen2] (net.js:1360:14)
    at listenInCluster (net.js:1401:12)

    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:189:7)

The funny thing is, that everything worked fine before. Then I restarted the fabric and reinstalled the bna file and now I get this error. Thanks for your help

It seems you have not stopped your script properly that's why this error is coming. This error comes when your port is already occupied and you are trying to start something on same port. So you can kill process on this port then it should work fine.

If you are using linux OS then this command might help you.

fuser -n tcp -k 3000
