When trying to establish a VPN (Virtual Private Network) connection, users occasionally encounter different types of errors. One of the most common and confusing among them is known as VPN Error 868. This error can be frustrating because it often halts the VPN connection altogether without giving the user much information. Understanding what this error means and how to fix it can help restore secure and uninterrupted connectivity with minimal downtime.
What is VPN Error 868?
VPN Error 868 is a Windows-specific error that indicates the client’s attempt to connect to the VPN server has failed because the remote connection was not established. Microsoft’s official line describes it as: “The remote connection was not made because the name of the remote access server did not resolve.”
In simpler terms, it means that the system is unable to resolve the domain name of the VPN server into an IP address. This issue is almost always related to DNS (Domain Name System) settings, misconfigured addresses, or network connection obstacles such as firewalls.

Common Causes of VPN Error 868
Several underlying issues can trigger this error. Here are some of the most frequent causes:
- Incorrect VPN server address: If the address is mistyped or outdated, the system won’t be able to resolve it.
- DNS resolution issues: DNS servers may be down, misconfigured, or blocked, preventing proper resolution.
- Internet connection problems: If there’s a general internet outage or network disconnection, the VPN won’t be able to connect.
- Firewall or antivirus restrictions: Sometimes, overly aggressive security software blocks the VPN ports or IP addresses.
- ISP-related restrictions: Some Internet Service Providers may block VPN services.
How to Fix VPN Error 868
Solving this problem typically involves checking the network settings and making sure the connection parameters are correct. Here’s a step-by-step guide for troubleshooting:
- Verify VPN Server Name
Double-check the spelling of the VPN server name. Make sure you’re using either a valid hostname (e.g., vpn.example.com) or a correct IP address. - Test DNS Resolution
Try to ping the VPN server via Command Prompt. Use: ping vpn.example.com
If the system cannot resolve the address, consider changing your DNS settings to use public DNS servers like Google’s (8.8.8.8, 8.8.4.4). - Restart Network Connection
Restarting your modem or disconnecting and reconnecting your Wi-Fi can sometimes resolve temporary networking glitches. - Disable the Firewall Temporarily
If your firewall is blocking ports necessary for VPN traffic (like port 1723 for PPTP), disabling it temporarily can help in confirming the cause. Be sure to re-enable it afterward. - Check VPN Configuration
Make sure that your VPN protocol and authentication settings are compatible with what the VPN server expects. Mismatches could lead to failures in the initial handshake.

Preventing Error 868 in the Future
Once the immediate issue is resolved, it’s worth taking steps to ensure you don’t face this error again. Consider doing the following:
- Set up reliable and fast DNS servers in your network settings.
- Keep a record of your VPN settings and make backups when changes are made.
- Ensure that security software is correctly configured to allow VPN traffic.
- Regularly update VPN client software to avoid bugs that could cause connection issues.
Frequently Asked Questions
- Q: Is VPN Error 868 specific to Windows?
A: Yes, it is primarily observed on Windows-based systems. Other operating systems have different error codes for similar issues. - Q: Can a malfunctioning router cause this error?
A: Yes, router misconfigurations or firewall settings can block VPN connections and generate error 868. - Q: Does reinstalling the VPN client help?
A: It can, especially if outdated configuration files or corrupt installations are causing the issue. - Q: Should I contact my ISP about this error?
A: Possibly. If you suspect the ISP is blocking VPN protocols, contacting them may clarify or resolve the issue. - Q: Can public Wi-Fi cause VPN Error 868?
A: Yes, some public networks block VPN traffic to control bandwidth or for security reasons.
Understanding what causes VPN Error 868 can help users troubleshoot and maintain stable and private access to network services. By methodically checking DNS, server address, and firewall settings, most users can resolve this issue within a few minutes.
