We have Kaspersky security center 12 (Kaspersky Endpoint Security for Windows 11.4.0.) and Kaspersky Security Center Network Agent. Windows Version : Windows Server 2019 Std. We use Hyper-V replication from primary server to secondary server which uses port 80 Kerberos for replication and both server have kaspersky. Now from past 3 to 4 days replication automatically stopped and port 80 is not reachable for primary to secondary so after troubleshooting i found that kaspersky is culprit after exit replication is working fine. I have checked polices “Firewall” policy is already disabled.
