ارور 811 برای کانکشن vpn

سلام

اکانتینگ اینترنت دارم، کاربرها با vpn وصل میشن، ارور 811 دارم روی یکی از کلاینت ها.

یعنی:

The network connection between your computer and the VPN server could not be established because the remote server is not responding. This is typically caused by a pre-shared key problem between the client and server. A pre-shared key is used to guarantee you are who you say you are in an IP Security (IPSec) communication cycle. Please get the assistance of your administrator to determine where the pre-shared key problem is originating.

بعد از نصب ویندوز 10 این مشکل پیش آمده. راه حلی به نظرتون میرسه؟
