To resolve the issue:

  1. Create a customized firewall rule allowing incoming TCP/UDP port listed on 3343 and 49152-65535.
  2. Assign the custom firewall rule to the target Deep Security Agent. The said ports are required for MS Cluster Service to allow multi-node communication between the MS Cluster Management Server and cluster nodes.
  3. You may change the Source IP value to Incoming Traffic instead of Any.

    Allow ports 3343 and 49152-65535

The nodes should now be working normally. For more information, refer to this Microsoft article: Service overview and network port requirements for Windows.
