We are using Fabricpool with Azure blob storage. From time to time, we receive object store unavailable error message. Upon further investigation, we could see firewall in Azure is dropping packets due to the reason of "First Packet not SYN". There are multiple cases open with vendors from NetApp, Firewall and Microsoft and none of them have found the issue so far. I am suspecting the Azure Load Balancer in front of FW nodes could be the culprit because session persistence is set to none but no one can really confirm this setting is required. I've exhausted all my options at this point and would like to know anyone have experience similar problem in the past.
