How to connect to couchbase with different port?

How to connect to couchbase with port other than default (8091).
Trying to connect couchbase://ct.com:3498 - > it’s not working in nodejs sdk

@Bala Did you check if the port 3498 is working? First try something similar to http://ct.com:3498 or https://ct.com/3498 in a browser and check if it is working. You can also look here Client Settings | Couchbase Docs and Couchbase Server Ports | Couchbase Docs for more information.
