重视隐私的活跃互联网用户应该投资使用VPN。良好的 VPN 服务(A good VPN service)可以帮助保护您的连接，并使所有在线活动对寻求将您的私人信息出售给出价最高者的阴暗网站保持匿名。如果您感兴趣，它们还可以让您绕过某些区域锁定的网站和服务。
与VPN(VPN)一样棒，它们也不是万无一失的。有时，连接可能无法建立，导致出现“连接(Connection)失败，错误 800”。这个错误是什么意思？
如果您碰巧看到此错误，则表示您的 Windows PC 上安装的VPN应用无法建立与VPN服务的连接。这一切的原因可以追溯到一些常见的嫌疑人，包括VPN应用程序配置、防火墙复杂性、您的互联网连接或VPN服务器的可用性。
如何修复 VPN 800 错误(How To Fix VPN 800 Errors)
要修复此错误，请确保您按照这些方法再次建立VPN连接。(VPN)
重启应用(Restart The App)
您已经尝试过这一步的机会很大。大多数人已经理解“关闭并重新打开”的方法。您所要做的就是重新启动VPN应用程序，看看它是否能解决问题。
但是因为您将按照编写顺序执行此处列出的所有方法，所以您需要重复此步骤。除了点击应用程序上的“x”来关闭它，您还必须进入任务管理器(Task Manager)将其关闭。
右键单击任务栏并选择任务管理器(Task Manager)。滚动进程选项卡以查找您的(Processes)VPN应用程序的任何实例。如果找到它，只需右键单击它并选择结束任务(End Task)以确保与您的VPN应用程序链接的每个进程都已关闭。
再次重新启动应用程序以尝试连接。
验证 VPN 设置(Verify The VPN Settings)
如果这是您第一次使用该应用程序，请确保您已正确输入用户名和密码凭据。它们必须与VPN(VPN)管理员 为您设置的用户名和密码相匹配。
检查VPN应用程序的设置，尤其是网络设置，并确保它们符合服务所需的设置。您应该能够在VPN服务提供商的网站上找到这些详细信息。
VPN服务的配置方式因服务而异。为确保应用程序设置正确，请与您的VPN提供商联系以获取任何必要的设置详细信息，以避免进一步复杂化。
端点服务器可能已关闭(Endpoint Server May Be Down)
在重新启动阶段之前，您应该检查您选择的端点服务器是否仍在运行。大多数VPN应用程序将允许您手动选择端点服务器，而其他应用程序可能会自动为您的互联网速度选择最快的路线。
选择与您当前选择的端点服务器不同的端点服务器。如果您能够在更改后建立连接，那么问题出在另一个端点服务器上。

设备重启(Device Reboot)
所以应用程序重启没有帮助，也许重启你的设备会。完全重启可以解决许多与网络和连接问题相关的问题。对于臭名昭著的Windows(Windows)网络问题来说， 这是非常正确的。
只需重新启动您的设备，无论它是 PC、平板电脑还是手机，然后查看VPN应用程序是否可以建立连接。
互联网连接问题(Internet Connection Woes)
此时检查连接状态似乎是更合乎逻辑的步骤。您在网上冲浪时是否注意到任何断断续续的连接？您使用以太网或WiFi连接吗？
您可以通过右键单击Windows 开始(Windows Start)按钮（位于桌面左下角）并从菜单中选择网络连接来开始状态检查。(Network Connections)
从这里，您需要从左侧菜单中选择以太网(Ethernet)或Wi-Fi ，具体取决于您使用的是哪一个。(Wi-Fi)无论您选择哪种方法，此方法的其余步骤都是相同的，但为了保持一致性，我将使用Ethernet。
选择连接后，在右侧的主窗口中，选择Change Adapter Options。
右键单击您的连接并选择Properties。
突出显示Internet 协议版本 4(Internet Protocol Version 4)，然后单击属性(Properties)按钮。将这两个选项设置(Set)为自动获取地址，然后单击OK。关闭所有剩余的窗口。
手动设置的 IP 地址可能与您的VPN的DNS或 IP 设置冲突。再次尝试建立VPN连接。
快速防火墙检查(Quick Firewall Check)
暂时禁用防火墙并重(Disable your firewall temporarily)试该应用程序。与防火墙相关的故障通常意味着防火墙配置可能需要特定于VPN端口号的其他设置。如果您的VPN连接，请确定VPN应用程序的可执行文件并允许它自由通过您的防火墙。
如果您仍然看到Connection failed with error 800，请再次启用防火墙。此时，问题可能出在服务器端。有时服务器可能会因为已经连接的客户端太多而陷入困境。
这并不常见，但限制可能会因服务器的设置方式而异。最好是稍后再使用VPN，或者与VPN管理员联系，让他们自行检查。
How To Fix VPN 800 errors
Active internet users who value their privacy should invest in the υse of a VPN. A good VPN service can help secure your connection and keep all online activity anonymous to shady websites seeking to sell your private information to the highest bidder. They can also allow you to circumvent some region-locked websites and services if that’s something that interests you.
As awesome as a VPN is, they are not infallible. There are times that a connection can fail to establish causing a ‘Connection failed with error 800’ to appear. What does this error mean?
If you happen to see this error, it means that the VPN app installed on your Windows PC is failing to establish a connection to the VPN service. The why of it all can be traced back to some of the usual suspects which include the VPN app configuration, firewall complications, your internet connection, or the availability of the VPN server.
How To Fix VPN 800 Errors
To fix this error, ensure that you follow these methods in order to establish a VPN connection once again.
Restart The App
The chances are pretty good that you’ve already attempted this step. Most people will already understand the ‘turn it off and back on’ approach. All you have to do is restart the VPN app in order to see if it corrects the problem.
But because you’re going to follow all methods listed here in the order they’ve been written, you’ll want to repeat this step. Instead of just hitting the ‘x’ on the application to close it out, you also have to head into the Task Manager to shut it down.
Right-click the taskbar and select Task Manager. Scroll through the Processes tab looking for any instance of your VPN app. If you find it, just right-click it and select End Task to ensure every process linked to your VPN app is shut down.
Restart the app again to attempt a connection.
Verify The VPN Settings
If this is your first time using the app, make sure you’ve entered in the username and password credentials correctly. They must match the same username and password set up for you by the VPN administrator.
Check the VPN app’s settings, network settings in particular, and make sure that they are in line with the setup the service requires. You should be able to find these details on the VPN service provider’s website.
VPN services are configured in different ways from service to service. To ensure that the app is setup correctly, check with your VPN provider for any necessary setup details to avoid further complications.
Endpoint Server May Be Down
Prior to the reboot stage, you should check to see if the endpoint server you’ve selected is still up. Most VPN apps will allow you to manually select the endpoint server whereas others may automatically select the fastest route for your internet speed.
Choose a different endpoint server than the one you currently have selected. If you’re able to establish a connection after the change then the problem lies with the other endpoint server.

Device Reboot
So the app reboot didn’t help, perhaps rebooting your device will. A full reboot has the power to fix many things related to network and connectivity problems. This is very true for Windows network issues for which they are notorious for.
Just reboot your device, regardless if it’s a PC, tablet, or phone, and see if the VPN app can establish a connection.
Internet Connection Woes
Checking the status of your connection seems like the more logical step at this point. Have you noticed any intermittent connectivity when surfing the web? Do you use an ethernet or WiFi connection?
You can begin the status check by right-clicking the Windows Start button (found in the lower-left corner of your desktop) and selecting Network Connections from the menu.
From here, you’ll want to select either Ethernet or Wi-Fi from the left side menu, depending on which one you use. The rest of this method’s steps will be the same regardless of the one you choose, but for consistency’s sake, I’ll be using Ethernet.
After choosing your connection, in the main window to the right, select Change Adapter Options.
Right-click your connection and select Properties.
Highlight Internet Protocol Version 4 and then click the Properties button. Set both options to obtain addresses automatically and click OK. Close out of all remaining windows.
A manually set IP address may conflict with your VPN’s DNS or IP settings. Once again attempt to establish a VPN connection.
Quick Firewall Check
Disable your firewall temporarily and retry the app. Firewall-related failures usually mean the firewall configuration may need additional settings specific to the VPN’s port numbers. If your VPN connects, identify the executable for the VPN app and allow it to pass freely through your firewall.
If you still see Connection failed with error 800, enable the firewall again. At this point, the problem could be server-side. Sometimes the server can be bogged down, having too many clients already connected.
This is uncommon but limitations may vary depending on how the server is setup. It would be best if you either wait to use the VPN at a later time or get in contact with the VPN administrator to have them check things on their end.
