Video Doorbell and Iphone. Can't accept calls with VPN on on Iphone

I am using a ARLO video Doorbell and when someone rings doorbell it rings my IPhone. I can’t answer it it just keeps ringing. That is with my Norton VPN enabled on the Iphone. If I turn VPN off it works great. I can accept the call and video is connected. Is it a VPN or Arlo issue

A VPN does not block anything. What you seem to be seeing is many web sites do not allow access from known VPN IP addresses. They do this for copyright, legal, security, and political reasons. There is nothing a VPN provider can or should do to circumvent these legal protections. See this How to Geeks article. https://www.howtogeek.com/403771/why-do-some-websites-block-vpns/ .

Check with ARLO’s support to see if they block known IP addresses.
