“There is no internet connection” error because of some wrong configuration of proxy is not suitable for anyone. It kills the purpose of having a device with everything but no internet connection. As we have discussed, the error shown on Google Chrome about being unable to connect to the internet because of some incorrect proxy settings is just the Google Chrome internal settings error, or it may be system-wide.

Even though it is not rare to find oneself in such a situation without tampering with any settings before this issue, it is more probable that a virus or some form of malware has caused this issue. The virus can penetrate a system through a downloaded installation file which did not come from a reliable source or an infected email. Even a secure looking pdf can be the source of the virus. In such cases, it is advised to first remove malware from Windows 10 and if that didn’t work then try to reset the system itself.

Plugins that contain malware or too many advertisements can be a sign of such a threat. So make sure you install plugins that were developed by some renowned developer and always check the user ratings before installing any application or a browser plugin.
