NordVPN connection problem (Need Help)

I have been using NordVPN routerOS 6.46 for a long while. Recently I checked the log and notice it no longer able to connect

Here is the log

03:17:57 ipsec,error can’t verify peer’s certificate from store
03:17:57 ipsec,info,account peer failed to authorize: 100.xx.xx.169[4500]-89.xx.

Does anyone know how to fix this? I have been using it no problem by following the guide on https://support.nordvpn.com/Connectivity/Router/1360295132/MikroTik-IKEv2-setup-with-NordVPN.htm

I don’t even notice it’s no longer working until recently I looked into the log.

As it says in the log it’s certificate-related or time-related. Maybe the certificate that NordVPN was providing was expired or changed however This is not a complete log for the connection enable your log for IPsec and share it. please do not share any sensitive data or Public IP.

thx, your comment is correct, it’s the date on the router is wrong. thanks.

you are very welcome.

as long as you have NordVPN details.
The rest of just do copy paste from MT wiki.
