SoftEther – Fixing connecting to localhost 5555

SoftEther VPN Server Manager Connection Issue:

I have used SoftEther VPN for a long time to connect securely to my cloud server for almost 2 years without any single issue and I am using my Laptop, iPad, Phone and everything without an issue.

But one day I tried to connect to the connection settings and I got this error

Softether VPN Connection Error

Connection to the server failed. Check network connection and make sure that address and port number of destination server are correct.


Attempts to solve the issue

I have tried couple of things that came to my mind maybe that would solve the issue.

  1. Uninstall and Reinstall Softether VPN.
  2. Uninstall and Restart
  3. Tried to create a new connection with different ports.
  4. Disabling Microsoft Firewall.


All of these attempts lead to failure and none worked eventually. So I started searching for a different solution and checked the configuration file of the Softether VPN server which is located in

File Location and Configuration

C:\Program Files\SoftEther VPN Server

You can open the file in Notepad and start looking for the default port 5555 which is how you could normally connect to the connection settings.


The solution is in the configuration changes, but in order to change/amend the config file you need to take a backup and make sure you stop the service before doing so.


Go to the configuration file location C:\Program Files\SoftEther VPN Server


Right click and open this file with Notepad


Search for uint Port 5555

On top of that, you’ll see bool Enabled false


Change that to Bool Enabled True

Save the file and start the service


Try to connect again


Now it works and will ask you for the old password which you had set previously


If you cannot remember the password, you can also find that in open text (Of course it is a vulnerability) then take it from there.


That’s it. You should be able to access your server settings now
