Node status is not ready after creating bucket 'couchmusic2' within 120 seconds

Couchbase Server

Hi,

I am learning couchbase and currently doing the CB110LabWorkbook45.

while trying to create a bucket and load the example json using cddocloader I get error. Below is the cmd output
C:\Program Files\Couchbase\Server\bin>cbdocloader -u Administrator -p password -n 192.168.1.106:8091 -b couchmusic2 -s 512 “c:\users\Shashi\cb110-Data-Win\couchmusic2-userprofiles.zip”
…
Node status is not ready after creating bucket ‘couchmusic2’ within 120 seconds

When I look at the the server page/console on the browser it says server down.
It also shows the new bucket ‘couchmusic2’ under bucket tab but there are no items inside.

Please advise.
