[strongSwan] Strongswan Connection Drop after 60 Minutes

That sounds like a rekeying issue (default CHILD_SA lifetime is 1h).
Possible culprits may be the DH groups in the ESP proposals if the peer
doesn't expect a DH exchange there (even though you added the default
proposal it might not be what the peer expects), see [1] for details.
Read the log to see what's actually going on.

Regards,
Tobias
