Hi, We are upgrading our Cassandra from 3.11 to 4. When we connect to the new Cassandra instance with our client everything is working fine however, we get this this error in the logs (SSL is not enabled and we are using the default cassandra.yaml):
ERROR [Messaging-EventLoop-3-1] 2022-08-18 14:10:34,707 InboundConnectionInitiator.java:360 - Failed to properly handshake with peer /192.168.32.1:40430.

I found this ticket<https://issues.apache.org/jira/browse/CASSANDRA-16144> that suggests if SSL is disabled, this error is produced, but it should be a warn or info log instead.
