Why does IPSec VPN hang after peer lifetime?

Question

Mikrotik

Good day. Launched IPSec VPN to the provider's server, everything is strictly according to the provider's settings. The problem is that after the expiration of lifetime from Peer Profiles, another pair of installed SAs appears in Installed SAs and work stops there, not a byte passes until you manually reconnect Peer. Proposal Check installed on Obey. Where to dig a dog?

Answer 1

And on the other side - isn't it racoon? I had this on FreeBSD - after the end of lifetime SA categorically refused to die and the first phase did not pass.
You can turn on verbose logging and see what's going on.
I always put strict.
