Troubleshooting

If connection cannot be established, check whether libreswan is installed or not. By default the NetworkManager-l2tp will use libreswan instead strongswan

$ sudo rpm -q libreswan

*// if returned libreswan version 
// ex : libreswan-x.x.x-x.fc35.x86_64
// proceed to the next step*

Switch to strongswan with the following command

$ sudo ipsec stop
$ sudo rpm -e libreswan
$ sudo dnf install strongswan

Switching between libreswan and strongswan helps from some weird compatibilty issue

To revert back to libreswan, just install it again with the following command:

$ sudo dnf install libreswan

When you switch libreswan to strongswan (or the reverse), make sure NetworkManger-l2tp isn't running. You can stop NetworkManger-l2tp with the following command:

$ sudo killall -TERM nm-l2tp-service
