Cube CRL Freeze
This BPA test identifies client machines and DataMiner Agents without internet access where the DataMiner Cube application experiences a significant freeze during startup. This freeze is caused by the system attempting to verify the application's digital signatures with online Certificate Revocation Lists (CRLs).
This BPA test is by default available in System Center from DataMiner 10.4.0 [CU19]/10.5.0 [CU7]/10.5.10 onwards.

Not Executed
Messages can appear when the test fails to execute for unexpected reasons:
- Result message:
Could not execute test ([message])."(on unexpected exceptions).
The test result details will contain the full exception text, if available.
Impact when issues detected
Impact: When an internet connection is not available on the client machine, the DataMiner Cube application freezes for about 20 seconds during the session. This happens because Windows and .NET try to verify the application's digital signatures by checking an online Certificate Revocation List (CRL). The system times out during this process, causing the delay and impacting user productivity.
Corrective action: To prevent these freezes, please consult your IT administrator. For detailed solutions and workarounds, refer to DataMiner Cube freeze on startup.
Limitations
This test is specifically designed for environments where client machines and DataMiner Agents lack an internet connection. The configuration problem and its detection are not relevant in online environments.
