Hi VGF5​ ,

I already saw this post, and although it looks similar, it reffers to VMware NSX environment which we don't use.

Today it happened again, and I noticed thatif I try to ping one of the VSs, it doesn't work, but after a few seconds if somehow "refreshes" the NIC and everything starts working again. Just like disableing/enabling the NIC in the VM.

    Thank you for the update. If this issue persists, I recommend creating new instances, testing them, and observing the traffic. If everything works as expected, add those two devices to the sync group and delete the existing instances.

      Maybe I wasn't clear but these are two standalone deployments and it happens on both of them randomaly, not at the same time.
