After following the steps to Manually Import TrustedCertList.pem or Keychain.json Files, the healthcheck does not go away:
Severity[medium]: Failed to download Server Cert List file from URL https://<ServerName>/packages/TrustedCertList.pem: Error[WinHttpQueryHeaders StatusCode[0000001F7]]
The manual import does not have logic in place to clear the health check. The message is only cleared on the next successful download.
This is being investigated and is currently tracked under CRE-18570.
