We installed a PA 3440 at a customer site which is being used to create a VPN tunnel with Azure. Two links have been configured in fail over mode (currently manual). The VPN tunnel fails randomly and needs to be rest manually. we have raised the case with PA who are struggling with logs since last 2 weeks without a fix. Basic configuration of the firewall alongwith settings on azure side have been verified by the PA L3, but there is no diagnosis. The customer is going live within 24 hours and is understandably upset with PA and us. can someone please throw a light on what could be the problem.
Also the tunnel works on one link (ISP-a) and does not work at all on the other link (ISP-b). this too is not diagnosed by PA L3. Need urgent help on both
