No longer able to Logon to my cameras app?

I can no longer log into my cameras app on my android phone. I have tried everything, resetting password, uninstalling an reinstalling the app. updating phone sofware etc. Now I am being told that it’s my VPN that is the issue? I have always used the same VPN and have never had a problem. So I have switched off the VPN and still having the same problem. Now I’m being told that I must uninstall the VPN as this is what is causing the issue. I am not prepared to do this just for Ring and then leave everything else vulnerable to hackers.
