Can you please run the following query on the problematic node?
select peer, host_id, release_version from system.peers where
release_version < '3.0.0' allow filtering;
I suspect you have a "ghost" 2.x node in the system.peers table on this
problematic node.
The "ghost" node will not show up in the "nodetool status" output,
because it does not exist except in the system.peers table.

Have you tried restarting your application? It should renegotiate the
protoco during handshake and should resolve the issue.

Someone asked me about the same issue a couple of months ago and
we never managed to figure out why the wrong version is being
displayed.
Could you try to run `SELECT native_protocol_version FROM
system.local`? It should come back with 4. Cheers!
