VPN on Android Won't Connect (Error 32801 and 12)

I know these questions are everywhere, but I can't seem to find an answer on here specific to the error message I'm receiving. I've been unable to connect to my VPN on my Android phone. When I try within the Central app, I get error 32801, and when I try in the separate VPN app, I get error message 12.

I've cleared the cache, reinstalled the app, all permissions are set correctly, I use no other VPNs... Nothing. Any ideas? Thank you!
