Have you tried req.ip?

req.ip

Contains the remote IP address of the request.

When the trust proxy setting does not evaluate to false, the value of this property is derived from the left-most entry in the X-Forwarded-For header. This header can be set by the client or by the proxy.

The req.ip and req.ips values are populated with the list of addresses from X-Forwarded-For

See Express 4.x API (About req.ip)

In case you are working with proxy, it requires a special application settings called trust_proxy (default is false)

NOTE: X-Forwarded-* headers are easily spoofed and the detected IP addresses are unreliable.

See Options for 'trust proxy' setting and Express behind proxies for more information

As GuroKing said, I am going to add one more point to it.

Add app.set('trust proxy', true)

In nginx.conf file:

proxy_set_header  X-Real-IP  $remote_addr;
