Hi, we have a Site to Site tunnel configuration with a 3rd party (Fortigate).
We are able to bring up the tunnel, but sometimes it will randomly go down, and the only thing I manage to find in the logs is the following :
Our public address - Remote public address - 443
IKE Failure : Encryption Failure : No Response from Peer
Action : Reject
(I'll link a screenshot in the post)
This Reject happens everytime the tunnel goes down. I don't know why it's trying to use HTTPS in a site-to-site configuration too.
Any ideas ?
Thanks!
