In general, the problem This site can't be reached may happens for failing on DNS lookup . DNS is that network address that translates the website name to its internet address. Most often it causes for not getting the internet connection or misconfigured internet or network settings. Another reason could be the firewall preventing Google Chrome to load the webpage. 

Here are some possible solutions, these solutions will try to minimize or remove the error completely and takes you to your desired website in your Chrome browser.
