CloudGuard Failure Issues in Azure
We have recently upgraded our R80.10 HA CloudGuard cluster in Azure to R80.20. We used the latest Azure marketplace template and have successfully deployed the two gateways to form the cluster. We successfully got everything configured and it has been working well. However, on two occasions now I have returned to work on the Monday morning to find that no traffic is flowing through to our IaaS estate in Azure through the firewalls. Upon checking SmartConsole I see red crosses and 'connection is lost' for both cluster members. On looking at the logs i see one last log originating from the Azure cluster member and the description is "(ClusterXL) interface enP1p0s2 of member 1 (10.12.2.8) was removed."
A restart of the gateway VM's in Azure brings them back to life but this obviously isn't a viable solution.
Has anyone had this issue before and can shed any light on it for us?
We are about to de-list R80.20 as described here: https://community.checkpoint.com/t5/CloudGuard-IaaS/Planned-Delisting-Announcement-for-CloudGuard-Ia...
