Summary

By default, Deep Security publishes new TLS inspection support to extend support coverage. When DSA version is above 20.0.0.7943 with IPS/WRS enabled, and 20.0.1.x TLSInspectionSupport package are imported, the issue occurs as it cannot use the latest TLS inspection support. The System Event shows the following:

The Agent/Appliance reported one or more warnings or errors. Details are found in the Agent/Appliance events listed below.

Agent/Appliance Event(s):

Time: January 4, 2024 06:50:51
Repeated: 6 times through January 4, 2024 06:51:11
Level: Error
Event ID: 5102
Event: Protection Module Deployment Failed
Description: Installation of Advanced TLS traffic inspection pattern '20.0.1-30' failed: Not available: netagent_pattern-linux-20.0.0.x86_64

The impact are as follows:

• The 20.0.0.x DSA version is above 20.0.0.7943.
• The System Events may be triggered hourly by the retry mechanism.

The root cause of this issue is that DSA 20.0.0.x cannot download the 20.0.1.x TLS inspection support module correctly.
