Dear Christophe KAUFFMANN,
Re-enrollment is not officially supported yet.
If you have a snapshot/backup before the last enrollment, it's the simplest way to go back to a clean proxy.
If you cannot revert back for any reason, you may have to manually clean up the proxy before you can re-enroll.
Try the following (but not 100% guarantee)
- delete portal users in Internal Identity Provider
- delete portal private keys
- delete portal certificates
- delete cluster wide properties for portal
- delete schedule tasks of portal
- delete Portal APIs (published from portal or from gateway)
(if still fail to enroll, re-do the above, and uninstall the Oauth OTK for portal)
Regards,
Mark
