Hello.
I make a DoH request via curl, it works.
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i curl -H
'accept: application/dns-message' -k 'https://dns.yandex/dns-
query?dns=AAABAAABAAAAAAAABG1haWwCcnUAAAEAAQ' | od -tcu1x1
I'm trying to make the same request through Indy, I get the message
Connection Closed Gracefully.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i HTTP:=TIdHT
TP.Create;HTTP.HandleRedirects:=True;HTTP.IOHandler:=SSL;HTTP.Request.
Accept:='application/dns-message';HTTP.Get('https://dns.yandex/dns-que
ry?dns=AAABAAABAAAAAAAABG1haWwCcnUAAAEAAQ',hsResponseStream);HTTP.Free
;
What am I doing wrong?

If curl is installed, simply use libcurl, which is supported as
standard.
It also works on Windows since 3.0.0. (I provided a patch, FPK
commited it)

I have attached an example program.
To compile, you need to install Indy from this pull request
https://github.com/mezen/Indy/tree/NewOpenSSL_PR

It is not clear why this request works through curl, but not through
indy
