I´m doing Mutal RSA with machine certificates, IKEv2.

Some clients are generating a lot of duplicate connections that do not seem to disapear for a long time, it's like 7-8 connections for each client.

Clients computer FQDN name show up as the ID. Offcourse only one of the duplicates are online, the other ones for the same computer are offline.

Why is this happeing? With most of the clients I don not get this behaviour.

Clients are Windows 10, newest release 20H2.
