Only Windows 10 has "Code 2 : Protocol Error occurred"

Post by RoweenX4 » Sun May 29, 2016 7:47 am

**Before I post this, I've read many topics regarding code 2 problem. But none of them helped me.

Could not connect - Error code 2 "Protocol Error occured"
This has been happening since April 2016 on Windows 10 Home 64bit
The problem occurs in every country I connect my VPN to.

VPN Version : vpngate-client-2016.05.29-build-9613.135602.zip

Things I've tried :
1. Some websites told that there's a problem with Date/Time but didn't give explanation on how to do with it.
So I checked "Regional and Date" in Windows 10 control panel. Update my BIOS and check if my system date is incorrect.
Set "Sync date with Microsoft server"
None of above solve the problem. I still got "Error code 2 : Protocol error occurred"

2. Check my Bitdefender Internet Security's firewall. There's an entry "Soft Ether VPN x64" something like that on the list and is set to "allowed"
I did even uninstall Bitdefender off my PC I still got the problem "Error code 2 : Protocol error occurred"
(I did the same for Kaspersky Internet Security and still got the problem too)

3. I have another PC running Windows 7 so I went on it and check. It **can connect to VPN just fine.**

4. I used some backup software to restore my Windows 7 back to my C: drive and try. Now I've been able to connect to VPN just fine until this day.

5. My dad has a Notebook running Windows 10 Home 64bit. So I've tried connecting VPN on it. And the same problem immediately occurred "Error code 2 : Protocol error occurred". (The same version off-course, occurs as soon as the installation process was finished)

Summary : VPN connection is okay on Windows 7 Home x64, no problem at all.
But with Windows 10 I can't use VPN to connect to anywhere. It says "Error code 2 : protocol error occurred". No matter how I try to fix this, it's still happening.

I have no idea what else to try.

Additional info - In case you think Antivirus software is suspicious :

Windows 10 + Bitdefender Internet Security 2016 : Error code 2 : protocol error occurred.
Windows 10 + Kaspersky Internet Security 2016 : Error code 2 : protocol error occurred.
Windows 10 without any antivirus : Error code 2 : protocol error occurred.

Windows 7 + Kaspersky Internet Security 2016 : No problem
Windows 7 with an expired Kaspersky Antivirus 2015 : No problem

Tested date : May 2016 period

Please refer to the thread

I have been using Windows 7 and it did not solve the problem at all.
I now gave up on SoftEther VPN and am using Open VPN without a single problem.
Funny, your Windows 7 worked, but not mine!

my asus laptop came with windows 10 home installed. i have had it for 2 years. now i am competent enough to start streaming broadcasting and burning content to cd/ dvd. but i could not get the optical drive to work, as well as the pc could notdetect other wireless devices. after hours of frustration i finally had microsoft tech get on my pc remotely to tell me what the problem was. my windows never had the software installed ion it.micro told me call asus. asus denied there was a problem and suggested 3rd party apps to make up for the missing software. m icrosoft laid down a new version of windows 10 home on my pc and everything is fine. as i understand it there were quite a few versions like this out there.
