Need compatibility with zScalar networking system

Issue/Introduction
After converting from a regular networking system to the zScalar system, users are getting a lot of timeout errors:
Unable to establish a remote connection (PEC ec=8)
Only disabling zScalar seems to resolve the problem, but this is a requirement so it cannot be a permanent solution. What can be done to allow Harvest to work successfully in a zScalar environment?
Environment
Release : 13.0.3 and higher
Component : CA HARVEST SCM INFRASTRUCTURE (BROKER/AGENT/PEC/SECURITY
Resolution
We used RT_FORCE_NODE_NAME to change the SCM Broker name to it's FQDN
Additional Information
We have found an important ZScaler setting that could impact the use of Harvest.
Secure Private Access (ZPA) Understanding Health Reporting
Health reporting is a feature in AppConnector (of ZScaler) which probes the open ports in the system and checks for their health. When the Harvest direct connection ports (that ones that PEC opens) are probed, they go into an inconsistent state (mostly CLOSE_WAITS) and that makes the connection unusable. Therefore only Workbench browsing happens, but no checkins or checkouts are possible.
To start, check to see if your Harvest configuration has a direct connect port range. To find out what that is, look in this file:
C:\Program Files (x86)\CA\SharedComponents\pec\standard\rtserver.cm
If you see a line that looks similar to this, the port range will be between the two highlighted numbers:
setopt direct_connect_port_range 9000,9100
In the example above, the port range is from 9000 to 9100.
If your rtserver.cm file does not have this setting then you will need to set this up so that Harvest has a defined range of ports to use for checkin and checkout. You can read more about port ranges here: Configure Enterprise Communicator (PEC) (look for the section titled "Port Ranges")
Once you know your Harvest direct connect port range, please request that your ZScalar administrator turn off health reporting for those ports.
