As the initiator, you won't see much detail. This is by design of IPSec - you don't want to give an attacker a bunch of details why it didn't work so they can figure out the right things that will work. See if you can initiate from the other side, or see the other side's logs if only you can do the initiating. Here are your logs with wrapping and monospace font: 2017-02-01 10:26:42 [PROTO_NOTIFY]: ====> IKEv2 IKE SA NEGOTIATION STARTED AS INITIATOR, non-rekey <==== ====> Initiated SA: 202.141.210.58[500]-213.152.246.225[500] SPI:fb7749a0549253cf:0000000000000000 SN:251 <====
