winhttp.winhttprequest.5.1 stopped working - error 401

[LoWang]

Hello, please advise how and if can I fix this. This code worked for several months but seems like something has changed on the server (cipher version maybe?) and it doesn't return anything now. I see that $oHTTP.Status contains 401.

$oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
$oHTTP.Open("GET","https://www.duolingo.com/2017-06-30/users?username=Marecustitus", False)
$oHTTP.Send()
consolewrite($oHTTP.ResponseText&@crlf)
consolewrite("http error: "&$oHTTP.Status&@crlf)

It appears that they are now filtering out requests that do not have a "valid" User-Agent.  By adding a User-Agent from any popular browser, it should work.  Other User-Agent strings may work too, like the default one sent by cURL (in my case "User-Agent: curl/8.0.1").  The example below is exactly the same as yours with the addition of a Firefox User-Agent header.  It worked for me.

$oHTTP = ObjCreate("winhttp.winhttprequest.5.1")
$oHTTP.Open("GET","https://www.duolingo.com/2017-06-30/users?username=Marecustitus", False)
$oHTTP.SetRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0")
$oHTTP.Send()
consolewrite($oHTTP.ResponseText&@crlf)
consolewrite("http error: "&$oHTTP.Status&@crlf)
