Whenever a VPN error occurs, it is normally a problem with the connection settings. Error 691 is a remote access error that will occur even if your connection is not dial-up. This has to do with the operation of the network layer of the OSI model, that is, it will use what is not broken. Since the error is caused by the same reason, the network layer will issue this Dial Up error even if the connection is not specifically a Dial Up connection.

Error 691 occurs when the settings are incorrect on one of the devices (client or server) and can not guarantee the authenticity of the connection. The most common cause is an incorrect user name or password. This may also be the case if you are using a public VPN and your access has been revoked, if you are trying to connect to the VPN with an unauthorized domain, or the domains are not allowed at all OR the security protocols necessary to the establishment of the connection do not match.

What Causes VPN Error 619?

When the computer tries to establish a new connection to a VPN server or when it is suddenly disconnected from an active VPN session, this error message appears. The Windows VPN client begins the login process, and then typically pauses at the "verify username and password" step for several seconds before message 619 appears.

How to Fix VPN Error 619 ?

Method 1: Allow Microsoft CHAP Version 2

Additionally, because this is an error with the VPN connection you may need to change the VPN properties in order to gain access. While changing the authentication level and encryption settings may help with the receiving end of the VPN connection, the problem may also be with the sending of the connection, which is why you might need to change the protocol for the VPN to connect with the VPN differently.

  • Hold the Windows Key and Press R. Type cpl and Click OK.
  • Right Click your VPN Connection and choose 
  • Go to the Security Tab, and put a check on the following two settings.

Method 2: Uncheck Include Windows logon domain from VPN Options

If the VPN Client is attempting to login with their domain, whereas the domain on the server is different or the server is setup to authenticate with just the username and password, then you may see this error.

  • Hold the Windows Key and Press R. Type cpl and Click OK.
  • Right Click your VPN Connection and choose  
  • Go to the Options tab, and uncheck “Include windows logon domain”

Method 3: Changing LANMAN Parameters

Usually, if the client has a newer OS and is connecting and VPNning into an older server then the encryption set on the client could also trigger this error.

  • Hold the Windows Key and Press R. Type msc and Click OK. Go to Administrative Tools -> Local Security Policy -> Local Policies -> Security Options and choose Network Security: LAN Manager authentication level and double-click it. 
  • Inside of Local Security Setting, change the option to Send LM & NTLM responses only.
  • Click
  • Then go toNetwork Security: Minimum Session Security for NTLM SSP and Click on it. Inside of Local Security Setting, disable the Require 128-bit encryption
