Add to First Data Cipher: AES-256-CBC
Other than that follow this guide: https://support.nordvpn.com/Connectivity/Router/1047410342/DD-WRT-setup-with-NordVPN.htm
set time zone and set Server IP/Name to: 216.239.35.4

Welcome to the forum

Look at the time of your router it is not working and without a current time the VPN will not work.

Just leave the IP/server name in the time settings blank (which is default) only set time zone.

Disable the VPN (no worries your settings are retained) reboot the router and see if the time is OK after that enable VPN and setup as @Foz111 said.

To get the best out of DDWRT and the forum read the forum guidelines with helpful pointers:
