Websites we visit are hosted on servers. Proxy servers are "middle" servers, which allow us to access the intended website, but as if someone else from a different locations tries to access it. These proxy servers are maintained by other people, and sometimes those servers can be brought down.

If you use a proxy server, to fix this error, you need to disable the server, or to switch to a different server. On a proper configuration, feel free to consult the proxy provider.

If Google Chrome core files were damaged, and none of the other solutions worked, the best course of action is to uninstall Google Chrome, and install it again. Even though some sources suggest deleting the current Google Chrome profile and readding it again, reinstalling Google Chrome and adding the profile is far more effective, with no margin for error.

To uninstall Google Chrome effectively, with no residual files left behind, feel free to check the instructions in the how to uninstall programs/apps guide.
