I am doing upgrade from 2.2.5 to 3.0.9 after completing upgrade on one of the nodes and I ran nodetool status it says the other nodes are down and when I ran nodesool describecluster it shows other nodes as unreachablenodes on AWS ec2snitch and when I ran nodetool status on other nodes they show they are normal but the upgraded node is down and when I ran nodetool describecluster on these nodes they show upgraded node as unreachable and when I check the peers table they still show the release version of 2.2.5 for the upgraded node which is supposed to be shown as 3.0.9.
