Trouble using Ring and Nord VPN

I've been using the Ring app on my iPhone 11, and it's been fine until today when I would get a Temporary Connection Issue. There seemed like no way to get into the app, via cell or wifi. I've been using NordVpn for quite a while and have previously had no issues using the Ring app with it connected. So I tried disconnecting Nord and now I can now get into the app. The Ring app definitely does not like Nord now for some reason... though other apps are functioning fine. Why is this a problem for the Ring? I should be able to use a VPN at my home and the Ring. Please fix!
