Hi Jason,
Are you able to provide the output of the failing health check at all? This might help us to troubleshoot the issue.
Also, it looks like the version of Tyk that you’re using is quite old and we do encourage our users keep up-to-date versions of the software in case they run into any of the bugs that we’ve patched in the past. It may be worth upgrading before attempting to run this health check again (the latest version of Tyk can be downloaded from this link).
Kind regards,
Jess @ Tyk
