Gateway monitoring 100% loss but Interface is UP and there isn't any packet loss

[autone]

I added a new WG interface to the existing one.

WG1 is the new WG interface. I've done everything exactly as I did for my original interface, WG0.

In gateway monitoring, WG0 works correctly, 0% loss. However, WG1, posts 100% loss no matter what monitoring IP I use.

Both WG interfaces are up and have successful handshakes. I know for a fact there should not be a 100% loss on WG1 but it is showing 100% loss.

Anyone has any ideas why this is happening?
