Hi,
Shortly after the VPN monitoring failure it complains about a TS unacceptable. I am sure these are symptoms related to a common problem.
> Could you share the ipsec config from the SRX340 side as well?
> Since you are montoring just the tunnel endpoints, VPN monitor does not provide a lot of benefit
> I would either try what was mentioned in the earlier post or remove VPN-monitoring completely to check if the problem is because of VPN monitor
> I am assuming reboot of the SRX300 is switching the Initiator responder role which may be bringing the VPN up
> Have you tried clearing the SAs on the SRX300 side to see if it fixes the issue - clear security ike sa
