Hi @prashantpawar723,

This is really weird. Is this a new droplet or some changes has been made to it?

Additionally, did you make sure to install the following prior to trying the command:

sudo apt install strongswan strongswan-pki libcharon-extra-plugins libcharon-extauth-plugins libstrongswan-extra-plugins
