Remote Access Issue - R9.0 and Up - Failed to Communicate

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.
 
This is why I have an old desktop sitting at the site. I just remote to it to do changes. One of my clients also has VM pro which is running on this same system for the files, etc.. for their complicated queue.

And yes, I was warned about RDP and potentially having issues, but we use screenconnect to get to the computer.

As for your specific issue, it does look like the VPN is only allowing certain ports to communicate which would be what is causing your errors. What specific VPN software is in use now. that might assist in figuring out a fix.
 
The VPN software is Palo Alto Prisma, thanks - should have included that in the post.
