For some reason I keep getting this error trying to set up AirVPN with wireguard. There is no place to put the preshared key though, not in advanced settings or anything. making a custom variable with 'WIREGUARD_PRESHARED_KEY" doesn't work either. Any thoughts? 2026-01-29T18:24:15Z ERROR VPN settings: Wireguard settings: pre-shared key is not set
