The "ghost" node will not show up in the "nodetool status" output, because it does not exist except in the system.peers table.

It should renegotiate the protoco during handshake and should resolve the issue.

Could you try to run `SELECT native_protocol_version FROM system.local`? It should come back with 4. Cheers!
