What is Error 628?

Operating Systems Affected: Windows (all)

This PPTP error occurs if port 1723 is blocked or closed, or if a response wasn't received from the VPN server.


  1. Ensure that PPTP pass-through is enabled on your router.
  2. Temporarily disable your firewall and/or other security software.

If step two above resolves the issue, contact Golden Frog support to get assistance updating your security software configuration.

If you are connecting to a network for which you are unable to modify these settings it may be necessary to change the protocol. You can upgrade your account, if necessary, here. Click on the "account" tab to access this feature.
