VPN Azure packet loss every 50 seconds

Question

Hi to everyone, we have an XG310 updated to last firmware XG310 (SFOS 16.05.5 MR-5). 
 We are experiencing this problem with Azure IPSec VPN: even if the vpn is connected , we lose 2 or 3 pings (about 5 seconds) exactly every 50 seconds, and so we lose RDP connections to Azure VMs. 
 Other vpns are running without any problem. 
 Any help will be greatly appreciated, thanks a lot 
 Alessandro

Hi Alessandro, 
 You may need to monitor this issue closely. 
 Steps involved. 
 Check the traffic through the IPsec VPN using the command 
 Console>tcpdump 'port 3389 and host <remote Location> 
 This traffic flow should be taken on both ends and you may compare the results on both ends Azure and XG . If there is a packet loss in between then you may need to contact your ISP . But if the traffic is not sent by XG into IPsec tunnel then collect your findings and contact support to analyze them and provide a session to verify the issue you have experienced.
