I'll post in one of the other threads too, but i updated my phone a month or so ago and found out that Android no longer supports the type of VPN that Unifi uses, L2TP. Sounds like this change happened a while ago, but things were grandfathered in.
I can't believe Unifi/Blue Iris would no longer work for half of us out there, so I'm guessing I'm operator error on my end.
