Based on the image you sent, the correct network port to its function in Conjur are:
22: required for SSH access
443: TLS endpoint for Conjur UI and API
444: HTTP health endpoint: simplifies load balancer setup
1999: audit events are streamed from the Follower to the Leader (using syslog-ng)
5432: required for data replication from the Leader to Standbys and Followers (PostgreSQL) These are the standard ports and protocols used by the Conjur components to communicate with each other and with external clients. The ports can be customized according to the network and security requirements of the organization. These ports are documented in the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2.
