I’ve followed these settings to setup a vpn server: https://help.uisp.com/hc/en-us/articles/22591226783639-EdgeRouter-L2TP-IPsec-VPN-Server
Yet I want to connect to this vpn server using network manager but it fails;
Yet it fails:

Mar 24 08:12:33 rhnmnb19572 NetworkManager[11886]: level=error tunnel_name=t1 function=transport message="frame receive failed" error="ignore data packet passed up from the dataplane"
