Your mention of VPNs is what worked for me. The Guardian VPN was getting me the "internet connection is not currently working" error message. I switched to my other VPN (yes, I'm cautious; I have two different VPNs) and was able to get in fine.
Hey neighbors. Just wanted to clear something up for you, but please note that Ring does not allow the usage of VPNs for the devices to be connected under, as well as use Ring.com or the Ring app with a VPN. As of December 2019, we no longer support the use of VPNs while accessing Ring, Rapid Ring, or Neighbors applications. In order to use these applications, we ask our neighbors to disable their VPN or ask their VPN provider to help them exclude Ring traffic from the VPN. In addition, you may see a 406 error message displayed when you try to log in to a Ring app via a VPN.
I spent 3 hours trying to connect and never did any of the ring help mention the VPN. as soon as I turned it off I got the abilty to connect. All is well now.
