Windows and private VPN companies are trying their best to work on known errors and their resolutions. However, at times the VPN functionality can give trouble in Windows. Most users face some or the other kind of issue with VPN connectivity.
One such error with VPN connectivity is when the remote server does not resolve. Earlier, with Windows 7, this VPN issue was symbolized by an error code 868, however, neither do we see the code now, nor is it mentioned in the recent error code list by Windows. The reason behind the error could be an issue with the VPN server or while connecting to the PC itself, the latter being more probable. Most issues with VPN give an error code, and the exact issue associated with the code can be checked at Microsoft. Knowing the error code can help you proceed with troubleshooting in the right direction.

If you face this error message, you can start with basic level troubleshooting before doing anything advanced. The following steps could be tried in a sequential manner’

Restart the system after running these commands. Try connecting to the VPN and check if it resolves the issue.
Step 2: Disable the firewall and the anti-virus
At times, the anti-virus software could interfere with the functioning if the VPN software. It is the same with the Firewall. To isolate the issue, we could disable or uninstall the anti-virus software and check if it resolves the issue. It could be re-installed or changed later.
To disable the Firewall you can follow this process:
1] Open Control Panel after searching in the Windows search bar.
2] Open the option for Windows Firewall.
3] Among the options on the left-hand side, choose the option which says ‘Turn the Firewall ON or OFF’.
4] Turn OFF the Firewall and save the settings by clicking in OK.

Sometimes, the Network might pose restrictions while connecting to a VPN client. Changing the network could help isolate the issue in this case.
If the steps mentioned above help resolve the issue with the VPN client, good enough, or else some advanced troubleshooting as mentioned here on Technet.
