Sometimes, the root cause is not SoftEther itself, but the Windows network stack. Previous VPNs or power outages can leave Winsock or TCP/IP in a broken state, triggering generic errors like Code 1.

If the standard SoftEther protocol fails with Error Code 1, you can still use the same free server by connecting via OpenVPN.

This bypasses the SoftEther client engine entirely while keeping you connected to the same free VPN network.

Error code 1 is fixable with the steps above, especially running as admin and reinstalling the virtual adapter. The free SoftEther client is powerful and reliable once running — just expect a small learning curve. If the error persists after trying all fixes, consider using the SoftEther VPN Server (free) to generate a working client config, or try an alternative free client like OpenVPN GUI (though less feature-rich).

Error Code 1 in the SoftEther VPN Client essentially means "Connection to the server failed". It’s a general network error that usually triggers when your client can't find or reach the server at the address and port you provided. 1. Check Server Address and Port

Double-check that the Host Name (IP address or DDNS) and the Port Number are exactly correct.

Common Ports: SoftEther typically uses ports 443, 992, 1194, or 5555.

Conflict Tip: Ensure the port you’re using isn’t already being occupied by another service like a web server (IIS/Apache). 2. Firewall & Antivirus Blocking

Often, a firewall on either the client or server side is blocking the handshake.

Test: Temporarily disable the Windows Firewall (or third-party antivirus) on both ends to see if the connection goes through.

Rule: If it works while disabled, create an "Inbound Rule" on the server to explicitly allow the TCP/UDP port you are using. 3. Router Port Forwarding

If your server is behind a router, it won't be visible to the internet unless you forward the ports.

Access your router settings and point the VPN port (e.g., 443) to the internal IP address of your server machine.

NAT Issues: If you have a modem and a separate router, you might be in a "Double NAT" situation. Setting the modem to Bridge Mode can often resolve this. 4. ISP Restrictions Always Error code : 1 when connect to the server
