SoftEther VPN User Forum

I'm having issue with the softether Server VPN.

The cert expiry date is 2030.
There's no changes on the softether server VPN. But suddenly, cannot connect to the VPN.

I have check the settings 1 by 1, there's nothing change.

I have tried change the port from the softether client side, port 992, 443, but still cannot connect.

How to solve?

I will subscribe and follow the discussion. I also have a problem. The settings do not change. But sometimes error 1 occurs when connecting the client. It arises and disappears on its own. I can't figure out the reason.

Since you use NAT-T, VPN connections are intermittent or none at all...

Btw, to only "change the port from the softether client side, port 992, 443,.. " is absurd.
