We have a customer who recently switched VPN access software, and since then we've lost remote access to all R9.0 and up systems. Instead, we get the dreaded "Failed to Communicate" error. Is this a security issue related to R9.0 and above? Ports, settings, etc? If so, is there a resolution? As an FYI, nothing has changed other than the VPN. Thank you in advance for any help.
