vpn error

VPN are the true protectors of online privacy in a very progressive age of surveillance, censorship and data breaches. While these tools secure our privacy and protect our data online there are always the bits & bolts that may malfunction at times.

On several occasions you may encounter errors while downloading, installing or using VPN on various devices. VPN errors occur due to various reasons like incompatibility with system settings, driver problems, inappropriate configurations, network issues, and invalid proxy settings among others.

VPN Error Code: 800

Error Description

Unable to establish the VPN connection

Cause

This error usually appears when the VPN tunneling type is set to ‘Automatic’ and thus establishing a tunneled connection fails.

Suggested Solution

First, confirm that your VPN username, password, and server address are correct just to be sure. Make sure that your antivirus software & firewall are not blocking your secure connection. Adjust the settings of the firewall and your router to ensure that GRE Protocol 47 is enabled or opened for PPTP VPN connection, and permit PPTP and/or VPN to pass via TCP Port 1723.

Windows users can also solve this error by changing the Type of VPN to PPTP through Security tab.  Sometimes this error may appear on your Mac devices, and you can solve it by removing http:// and / from the server address.

VPN Error Code: 633

Error Description

Port Already in Use or is “not configured” for Remote Access Dial Out.

Probable Cause

This error appears if the TCP port is already in use by any other program. TCP Port 1723 is used by VPN software to establish a connection, and if it’s already in use then VPN will be unable connect.

Suggested Solution

This problem can be resolved by restarting your device.

 

VPN Error code: 806

Error Description

A connection between your computer and the VPN server has been established but the VPN connection cannot be completed.

Probable Cause

This error appears when an internet device between VPN server and your device is configured to restrict GRE or Generic Route Encapsulation packets. This error may also appear due to slow internet connection speed. GRE is a Cisco Systems technology designed to encapsulate data over different protocols.

Suggested Solution

Check your router and/or firewall to ensure that they are not restricting GRE packets. Moreover, do confirm if you can reach the VPN server by pinging it manually, this would determine if the error has appeared due to poor speed.

 

If you are using Wi-Fi to connect to VPN then you should also check your Wi-Fi Router Panel to ensure PPTP, L2TP and IPSec protocols are enabled. These options can be accessed through the Firewall or Security section (depends on router make & model). You should also look at your firmware and if it’s old and not compatible then you should consider updating it. Finally, you should also check if a particular software is blocking GRE packets.

VPN Error code: 868

Error Description

The remote connection was not made because the name of the remote access server did not resolve.

Probable Cause

This error appears when you are using the wrong server name or when there is a problem with resolving DNS.

Suggested Solutions

First, ensure that you are using the right server names.

If the error is still appearing, then change DNS settings on your device (consult your VPN provider’s support & live chat). Try to establish a connection with VPN by using the server IP address instead of using the hostname.

VPN Error Code: 628

Error Description

The port is disconnected or the connection was terminated by the remote computer before it could be completed.

Probable Cause

The most probable causes for this error are modem issues, noise in the phone line or port blocking issues by the ISP.

Suggested Solutions

Have your phone line checked for noise and other problems. If the problem persists then update your modem or router firmware just to be on the safe side. The problem can also be fixed by reinstalling modem drivers or re-enabling RAS. Check your login credentials, and settings of firewall or router.

Always ensure that your router is allowing GRE packets.

 

VPN Error Code: 624

Error Description

Cannot write or update the phone book file.

Probable Cause

This error appears on Windows when the operating system cannot update or write information to “.Pbk” (phone book file). This happens when the file is damaged or has been configured to read-only settings.

Suggested Solutions

First, you have to locate the phone book file Rasphone.Pbk, which you are likely to find in System32 folder (Windows OS). Once you find this file, check its properties if it is set to read-only or not. If not, then it is highly likely that the file is damaged. To resolve the damage file issue, first of all rename the damaged “.Pbk” file to “.Pbk.old” and run the setup or .exe file again.

VPN Error code: 647

Error Description

The Account is disabled

Probable Cause

This error may appear because of excessive sessions (connecting & disconnecting more time than allowed by provider), payment verification issues or connecting the VPN account on more than the allowed devices. Sometimes incomplete or missing financial information can lead to this as user payments are not made.

A VPN error 647 also occurs if you connect VPN on more than allowed devices, usually most VPN providers offer connecting 2 devices simultaneously, while other premier brands offer connectivity up to 5 devices using the VPN app on Windows, Mac, Android and iOS devices. PureVPN and IvacyVPN offer connectivity over 5 devices, while TotalVPN & SaferWeb VPN allow connectivity over 2 devices.

Suggested Solution

Before disabling your account, the provider will send you an email mentioning the reason for such action, always check your email in case you face this issue. Follow the instructions provided and reactivate your account. Disconnect any additional devices you are trying to connect and try over your PC or mobile first.

VPN Error code: 766

Error Description

The error 766 may appear with one of the following messages:

  • A certificate could not be found.
  • The L2TP connection attempt failed because the security layer could not authenticate the remote computer.
  • A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate.

Probable Cause

This error appears when the device fails to authenticate the machine or computer certificate. Remote access servers that are configured with L2TP/IPSec typically generate this error when the remote access service starts the machine or device fails to present the computer certificate. This certificate is necessary to authenticate and allow you to connect using L2TP VPN protocols.

Suggested Solutions

You need to select Automatic in the VPN Protocol type option if you are using PPTP VPN. However, for L2TP protocol you need to look for a certificate from the computer certificate store. You can always install the certificate yourself, but consider help from your VPN provider for this.

You should consult the VPN provider’s Live Chat service for help if you are unsure.

VPN Error code: 807

Error Description

The network connection between your computer and the VPN server was interrupted.

Probable Cause

You may encounter this error due to the issues with VPN data transmission. Commonly, the problem with VPN transmission is caused by internet latency. Moreover, when your VPN server reaches its maximum capacity, then this error may appear.

Suggested Solutions

First of all, disconnect your VPN then switch to a different server and then reconnect. If the problem stays, then one of the following methods will remove this error:

  • Disable your firewall and antivirus
  • Delete/Clear browser cookies
  • Recheck your VPN address and login credentials, and login again
  • Change your connection type to PPTP VPN, or
  • Remove http:// and / from the server address.

VPN Error Code: 711

Error Description

Cannot Load the Remote Access Connection Manager Service.

Probable Cause

This issue appears when one of the services mentioned below are disabled:

  • Remote Access Auto Connection Manager,
  • Remote Access Connection Manager, and
  • Telephony

Suggested Solution

This problem can be resolved by enabling the disabled services. To do this we highly recommend consulting your VPN provider. One wrong tweak can cause issues in your OS.
