Coordinator node timed out waiting for replica nodes in Cassandra Datastax while insert data

When I try to Insert data in Cassandra using the below query I am getting the below mentioned error

cqlsh:assign> insert into tblFiles1(rec_no,clientid,contenttype,datafiles,filename) values(1,2,'gd','dgfsdg','aww');

WriteTimeout: code=1100 [Coordinator node timed out waiting for
replica nodes' responses] message="Operation timed out – received only
0 responses." info={'received_responses': 0, 'required_responses': 1,
'consistency': 'ONE'}

My Version of Cassandra and DSE:
[cqlsh 5.0.1 | Cassandra 2.1.5.469 | DSE 4.7.0 | CQL spec 3.2.0 | Native protoco l v3]
