Hi, I am running the latest version of SoftEther VPN Client on my Windows 8 PC. It was working fine until about a week ago when I started getting an error saying this:
«Error (Error Code 2):
Protocol error occurred. Error was returned from the destination server.»
I have ran the application as an administrator and I still get the error. I have tried allowing SoftEther access to port 443 in my firewall settings and I still get the error. I have tried reinstalling and I still get the error.
I checked my network activity in Kaspersky and closed all applications using port 443 other than SoftEther (in this case, I closed Skype, LINE, Flash, and FireFox). I still got the error.
The only thing that seems to allow me to connect to a VPN is using UDP instead of TCP, and even that only allows the connection to last 5 minutes before I am suddenly disconnected for no apparent reason at all.
At this point I am at a loss, I don’t know what else to try. Could anybody help me?
Required Info:
OS: Windows 8.1 64-bit
SoftEther version 4.1 build 9473
I do have a firewall, but I’ve done everything I can think of for changing the rules to allow connections through (though it was that way in the first place) and it still did not work.
not using SecureNAT (to my knowledge anyway)
Can’t find vpn_server.config or vpn_bridge.config, maybe because I’m only using the client and not the server?
Using VPNGate plugin for all connections.

I installed latest version of (SoftEther VPN client + VPN gate plugin). I have win 10.
when I want to connect with TCP mode immediately error code 2 appears.
«Error (Error Code 2)
Protocol error occurred. Error was returned from the destination server.»

I can connect in UDP mode But I want to use TCP mode.
It’s interesting that my friend by his PC connect without problem…
Thanks.

So to fix this annoying problem you want to go to hidden icons or find the softether VPN icon in your taskbar right-click it and press exit and then yes then go to the search bar in you computer and search up services find SoftEther VPN and double click it now click stop then click start again if that didn’t work then go to time.is on your browser and see if your time’s correct if it’s about 40-60 seconds late maybe below that’s fine, hope I helped you!

another way of solution:
- Open the «SoftEther VPN Client Manager» window.
- Right click «VPN Client Adapter-VPN», then click on «Reinstall driver…».
- Click «Ok» & do nothing until finish the process.
- After finish the this, Try your SoftEther VPN Client service without problem.
Hope you got the answer.

Press «Proxy Settings» choose a section «Connect via HTTP Proxy Server».
In the settings, enter any name and okay.
This worked for me.

Softeher ‘Error occurred. (Error code: 2)’ sollution
Protocol error occurred. Error was returned from the destination server.
The Softether server by default to run on port 443, if you server also hosts normal https then 443 is already taken and so Softether can’t bind to it.
When you run `vpncmd` it attempts to connect, find an active port, but of course fails with ‘Protocol error occurred. Error was returned from the destination server.’ because it’s not actually connecting to the vpn server.
By default Softether also listens on 992, 1194, and 5555 so the sollution is to modify specify `localhost:5555` when executing the `vpncmnd`. If this has helped you feel free to comment or follow me on twitter @danielsokolows.
