Start with CVECheckService.retrieveVulnerabilityData at line 312, then trace the callers fetchCves, getCveUpgradeIssues, and batchGetCVEIssues shown in the stack trace. Reproduce the Windows 11 connection failure and determine the expected outcome when GitHub Security Advisory API access raises ConnectException; done means the failure is confirmed and appropriately addressed or documented.
