When you update to Windows 8.1 and Internet Explorer 11, some sites may be unreachable. You may be unable to connect to certain wireless networks in coffee shops, schools and so on. Additionally, you may receive the following generic error message:

This page can’t be displayed

Note This is a generic error page of Internet Explorer. So, you could receive it for many other reasons.


This issue occurs because the navigation or connection fails when Windows 8.1 and Internet Explorer 11 first attempt to connect to a secure site or server by using a cipher suite that is not based on RC4 to improve security. This is because researchers have recently shown that RC4 is susceptible to exploits. As per TLS negotiation rules, servers are supposed to give an appropriate response to the client if they require RC4. Unfortunately, some servers are buggy and do not negotiate or fallback correctly.


After you apply the hotfix, when the first negotiation fails, Internet Explorer 11 will attempt to connect to these servers that use TLS 1.0 with RC4 enabled. This fix makes sure servers that use more secure cipher suites do not use RC4 and those servers that respond unfavorably are still reachable to users.
