VPN Server and Client Issue

Post by danishhazwan » Sun Jan 11, 2026 4:42 am

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.
