Site2Site pfSense <> Cisco, "down" after 24h

[Macormick]

Hello,

I have a Site 2 Site to a Cisco router, it´s IKEv2. Phase 1 and then 3 phase 2.

Phase 1, 86400s
Phase 2, 28800s

It looks like P1 is up but only 1 of the 3 P2 are up after 24 hours, and it varies wich P2 that is down.

When I restart ipsec and then connects the tunnels, it works, but fails again after 24 hours.
