Start in CVECheckService.java at retrieveVulnerabilityData (line 312), then trace fetchCves and getCveUpgradeIssues using the reported stack. Determine how the IntelliJ plugin should handle a ConnectException from the GitHub Security Advisory API; completion requires an agreed failure behavior and verification that the uncaught error no longer occurs.
