CQLSH ProtocolError

Question

I have an error with cqlsh when I type cqlsh to start cassandra shell where cassandra server is already started this error appears

Connection error: ('Unable to connect to any servers', {'127.0.0.1': ProtocolError("cql_version '3.3.1' is not supported by remote (w/ native protocol). Supported versions: [u'3.4.2']",)})

I also already installed cassandra-driver and export CQLSH_NO_BUNDLED=true but nothing changes could anyone have any idea to solve this ?!! my cassandra version is 3.6

The protocol version you are connecting is not supported by the version of your cassandra's protocol

Try adding --cqlversion="3.4.2" as argument in cqlsh

bin/cqlsh --cqlversion="3.4.2"
