2. Check yourVPNIP address, username, and password
Connection failed witherror800message can appear if yourVPNconfiguration isn’t correct. This can occur if yourVPNIP address, username or password aren’t correct. If you want to check yourVPNconfiguration, you can do that by following the steps above.
It’s important to mention that yourVPNaddress can’t havehttp://or/in its name, so be sure to remove it. For example, change thehttp://yourvpnaddress.comtoyourvpnaddress.com. After making the necessary changes, try to connect to yourVPNconnection again.
3. Check your router and firewall settings
If you’re getting the VPN connection error 800, we advise you to check your router and firewall settings. According to users, you need to allow for PPTP and/orVPNto pass through TCP Port 1723.
In addition, GRE Protocol 47 must be opened for PPTPVPNconnection. After making those changes, check if the problem is resolved.
Some users are also suggesting to temporarily disable your firewall and check if that solves the problem.
If the problem is fixed after disabling the firewall, it means that there’s a problem with your firewall configuration.
We have to mention that you should never keep your firewall turned off because it makes your PC and your network vulnerable.
If this problem is caused by your firewall, turn the firewall back on again and check its configuration.
It’s worth mentioning that other third-party security software can also cause problems withVPNconnection, so you might want to temporarily disable your antivirus and check if that solves the issue.
We also advise you to check if the router or firewall supportsVPNconnections. Some devices don’t work withVPNconnections, so you’ll have to install a firmware update in order to useVPN.
In addition, be sure to check if the router supports PPTP Pass-Through.
4. Change the type ofVPN
According to users,VPN error 800 can appear due to yourVPNsecurity settings. To fix this problem, you need to locate yourVPNconnection and change its security type. This is rather simple and you can do it by following the steps above.
5. Check the connection between the client andVPNserver
In addition, you can also wait for a few minutes and try to connect again. If the problem still persists, you might want to try using a different client, such as a different PC, in order to connect to the server.
If you’re unable to connect to the server from a different PC, it means that you have network configuration problems or that theVPNserver is having some issues.
Connection failed witherror800message can appear if there are any connection problems between the client and the server. To check if there are any network issues, you can ping the server and wait for the response.
6. Check forVPNserver limitations
SomeVPNservers have limitations when it comes to the number of connected clients. If the maximum number of clients is connected, you won’t be able to connect and you’ll get theConnection failed witherror800message.
This is an uncommon problem, but if you’re a server administrator, you can check for server limitations and change them if necessary.
7. Restart your PC and your router
Sometimes in order to fixConnection failed witherror800message you just need to restart your PC and your router. First try restarting your PC. If that doesn’t help, you need to restart your router.
To do that, press the Power button on the router to turn it off. Wait for 30 seconds and press the Power button again to turn it on. After restarting the router, check if the issue is resolved.
If the problem still persists, you might have to upgrade your router firmware. This is an advanced procedure, so before you do it we strongly advise that you check your router’s manual for detailed instructions.
8. Check if Routing and Remote Access is running on the server
If you’re getting the VPN error 800, this might be because Routing and Remote Access isn’t running on the server. Sometimes this feature can turn itself off and cause this and many othererrorsto appear.
If you’re having this problem, be sure to turn on Routing and Remote Access on the server. After turning this feature on, check if the issue is resolved.

6.Now double click thehostsfile to open it.
7.Once the host’s files opens, add at the bottom of it the IP address of your VPN server along with the address that you want to use.
We use192.168.1.1 thisismyvpn.comin our example.
-
Save the changes you made to your file.
-
Now try to connect to your VPN by usingthisismyvpn.comor any other address that you specified in the previous steps.
According to users,Connection failed with error 800message appears if you try to access the VPN server by using its IP address. To fix this problem, you need to use a regular address instead of an IP address. To do that, you need to add the VPN’s IP address to the hosts file in Windows 10.
This is relatively simple, as shown in the steps above.
10. Contact your ISP
Few users reported that this issue can occur due to problems with your Internet Service Provider. If you suspect that the problem is related to your ISP, be sure to try using a different modem.
According to users, some ISPs block GRE protocol remotely, and that will causeConnection failed witherror800message to appear. To fix the problem, you need to contact your ISP and ask them to unblock GRE protocol.
