You can attempt to ping the server if you aren’t sure, although VPN servers can be configured to ignore ICMP requests. Retrying the connection after waiting a minute or two can work with sporadic network outages. Attempting a connection from a different client device can also help pinpoint whether the connectivity issue is specific to one client or if it is a widespread problem.
Make sure your VPN name and address are correct – they should match the ones set by your VPN administrator. The point is, you might have accidentally mistyped them. Besides, some VPN servers occasionally change their addresses.
To determine whether a client firewall triggers VPN error 800, temporarily disable it and retry the connection. Firewall-related failures indicate a need to update the firewall configuration with additional settings specific to the port numbers the VPN on that network uses—usually TCP port 1723 and IP port 47 for Microsoft Windows VPNs.
