I have problems using IKEv1 / IKEv2 on MAC OSX, after a re-key the tunnel disconnects after a couple of minutes. On Windows it works fine.
We have received feedback from customers that this seems to be a known issue since OSX version 10.12 and up. The problem is when using Perfect-Foward-Secrecy (PFS) on Phase-2. Until such time that Apple has fixed the problem, the solution is to allow "none" to be used on PFS. See below picture for an example.
