Then that's the cause for the node negotiating down to an older protocol
version by design for dealing with mixed-version clusters as Sam described
in his response. As Bowen stated, you must have had an old node back from
when it was still a C* 2.2 cluster that you probably tried to
remove/decommission but ran into issues so it's still hanging around in
gossip.

You can manually delete that node to get rid of it with:

cqlsh> DELETE FROM system.peers WHERE peer = '10.39.36.152';


There's a good chance that you need to delete it multiple times -- it's a
race with gossip re-populating the table. Also check that it's completely
gone from nodetool gossipinfo. Once you're convinced that it's no longer in
gossip and in peers, you'll need to restart the node so it defaults back to
v4. Good luck!
