Ipsec errors for multi office vpn

ollieholroyd

Hi all

strange issue that I am having. I have a multi site setup with multiple vpn tunnels between them.

Problem is that 2 tunnels at each end are showing they are working. but they are not. ( they have worked prior to today )

I get these errors a lot in the logs and wondered If anyone could shed some light or point me in the right direction
