An error 619 is something which occurs with PPTP setup on Windows machines. Basically, a 619 Error means there is a Firewall somewhere in your network setup (either a software firewall or a hardware-based firewall) which is blocking all PPTP traffic.
Here are some things you can do to resolve the error:
- Make sure you do not have any Firewall software running on your computer.
- Check your Wifi router (if possible) to make sure PPTP traffic throughput is enabled.
- Install OpenVPNinja and use this method instead of PPTP.
