Common VPN connection problem on Windows client

If you are not able to login the App, or cannot load SimpleLink proxy servers in the App, please go to User=> logout, and then exit the app.

If you can’t exit, please User=>clear cache, or right click the Simple icon in the bottom right task bar, or ctrl+alt+del to force exit. Then reboot your PC and restart SimpleLink app and re-login.

If this doesn’t solve the problem, please completely eliminate your current SimpleLink app in the Control Panel. Then reinstall the new version:

https://appdown.simplelink.site/down/SimpleLink_windows.exe

Do not install SimpleLink in a directory that is named with special characters, space, or in Chinese.

Make sure the time on your windows system is synchronised as Beijing Time. Otherwise the app will not work.

Please also make sure when you install the new version, windows firewall, windows defender,  antivirus software are OFF or they give green light to SimpleLink. Most importantly, there is no other VPN app running or open in the background. 

After re-installation, please try again.


If SimpleLink App can load servers correctly, but cannot access the Global Internet after switching on the VPN connection, what shall I do?

First of all, make sure that you are using the latest version Windows app. If not please completely eliminate your current SimpleLink app from the Control Panel.

Then reinstall the new version:

https://appdown.simplelink.site/down/SimpleLink_windows.exe

Once you have the latest version installed and system reboot,

  • Make sure that all other proxy plugins are uninstalled on your browser;
  • Configure Windows firewall, Windows Defender and antivirus software. Let them give green light to SimpleLink;
  • Make sure that there is no malicious software such as 360 in your computer, otherwise they may cause SimpleLink not work;
  • We recommend use Chrome, Safari, Firefox as your Internet browser. Download link below;
  • Close and uninstall other VPN software to prevent conflicts between VPNs;
  • Make sure that your subscription is still valid and there is still remaining data available (not showing a negative number). If you are not sure about it, check User Center;
  • More sure the number of devices connected is within the allowed number. If you are not sure about it, check User Center;
  • Try use a different server location;
  • Restart the computer; log out, close and restart the SimpleLink client, re-login, click the refresh button;

You may also want to click the app setting button at the bottom left of the UI, turn on TUN mode, and then disconnect, close, and reopen SimpleLink, select the server and try again.

If you still cannot access websites such as Google and Youtube after the above operations, do the following:

Your Windows may have blocked SimpleLink App and its communication with SimpleLink API and servers. It is also possible that you have some network or proxy setting is not common(abnormal) on your system.

In this case, we suggest you use another app called Clash for windows, which is more compatible with most Windows versions and environment and it is compatible with SimpleLink servers:

Please login to User Panel and following the instruction: Clash for Windows.


If you use other browsers, please change to Chrome or Firefox.

If the connection still fails, please describe the system environment and browser version, whether the system has anti-virus software or security guards, and send screenshots of SimpleLink client interface to our customer support.
