Error: failed to connect

[diwalker]

Mongo running normally, but when I run npm start in the folder, this error appears just below, and http: // localhost: 6868 does not open, but the mongo is running. I'd like some help to find out why.

npm start

[email protected] start /home/dking/Documentos/HubTaxi-Server
node server

connect.multipart() will be removed in connect 3.0
