Start in CVECheckService.java at retrieveVulnerabilityData(), then trace fetchCves(), getCveUpgradeIssues(), and batchGetCVEIssues() to understand the failing request path. The report does not specify a code change or expected behavior, so confirm how network-unreachable errors should be handled and what test or user-visible result would define completion.
