Start in CVECheckService.retrieveVulnerabilityData at line 312, then trace the fetchCves, getCveUpgradeIssues, and batchGetCVEIssues callers shown in the stack trace. Reproduce the connection failure in the reported IntelliJ and Mac OS X environment if possible. The report does not specify a target change, test, or completion criteria, so those need clarification before implementation.
