Hi, we upgraded from Zookeeper 3.9.1 to 3.9.2. TLS was configured before the upgrade. No TLS version specified as part of zoo.cfg. Post upgrade, client to server connection is broken with TLS error (The client supported protocol versions [TLSv1.2, TLSv1.1, TLSv1] are not accepted by server preferences [TLS13]). Looking at the logs, client is using TLS 1.2 and but it looks like server is forcing to use TLS 1.3. Its IBM JDK. Post this, made below changes to zoo.cfg and client-server connection worked fine. ssl.protocol=TLSv1.2. Is this a new change in 3.9.2 which forces to use 1.3 by default? Thanks Jeetendra
