visual studio 2019 f1 help not working

Anthony Weathers 46 Reputation points Microsoft Employee

When I use the F1 key with a function name highlighted, the web page indicates the request was blocked. The link the browser is trying to access is:;k(_wtoi);k(DevLang-C%2B%2B);k(TargetOS-Windows)&rd=true

and the response is:

The request is blocked.

I get the same type of response if I strip the URL down to

Visual Studio
Visual Studio

    Hi @Anthony Weathers ,

    Welcome to Microsoft Q&A forum.

    Which version of Visual Studio 2019 are you using? I notice that this issue was reported before and was fixed in Visual Studio 2019 version 16.6. If you are using a lower version of VS 2019, I suggest you try to update to use a higher version of VS 2019.

    If you are using a higher version of Visual Studio 2019, could you help to confirm whether this issue appears for other codes and other projects in VS 2019?

    Best Regards,

    same problem here too.

    Had that problem a week ago and removing cookies (or using an InPrivate session with the link) worked for a couple days. The issue studently returned moments ago and now even InPrivate is not working.

    Microsoft Visual Studio Professional 2022 (Pro) (64-bit) - Preview Version 17.2.0 Preview 3.0

    For me the same problem, clearing all cookies works for mee
    it has nothing to do with Visual Studio, it has to do with cookies / login info edge is sending clearing the cookies (all sites) helps

    I had this problem using ipv6.. Has it to do with country's blocking ?
