AR750S - no internet when connected to one VPN provider, other works fine

Suddenly I can’t load sites when connected to Wireguard client VPN through starVPN. Changing it OpenVPN works fine (though much slower), and changing to a different VPN provider through wireguard (mullvad) also works. The VPN says it’s connected, and shows data up/down, but sites don’t load.

I’ve tried reverting firmware, re-adding the VPN, etc.

IP Address
Private Key redacted
Listen Port 11033
MTU Peer
Public Key redacted
Endpoint Host
Allowed IPs
Keep Alive 25

Config file:

PrivateKey = redacted
Address =

PublicKey = redacted
Endpoint =
AllowedIPs =
PersistentKeepalive = 25

I’m adding the VPN according to these instructions: Wireguard VPN Setup on GL.iNet Router - StarVPN

Are you using 4.X firmware? We’re going to test recurrence.
