CouchBase 4.0 Mac 10.12 Server Problem

I am new to couchbase server. I have installed couchbase server and I moved that to the application. I got the couchbase icon in rightside menu bar. there Launch Admin Console at Start is clicked and Automatically start at Login is unchecked. I try to open admin console but I got site can’t be reached. whenever I open the Couchbase Server in application I feel nothing is running. I got some log.

  • I got this log repeatedly.
