Not able to restore backup using cbrestore

I am getting the following error while restoring backup using cbrestore.

error: async operation: error: MCSink MC error: 135 on sink: http://localhost:8091(mybucket@localhost:8091)
error: MCSink MC error: 135

./cbrestore /mnt/backup-20180220 http://localhost:8091 -u username -p password --bucket-source=mybucket --bucket-destination=mybucket

How can i resolve this ?
Thanks in advance.


-v, --verbose Verbose logging. More v’s provide more verbosity. Max: -vvv.

What does it say when you put the command in verbose mode.
