Hi.
The source is below.
When I execute it I get an exception:
Connect to github.com:443 failed.

The URL is okay, what could be wrong?
This code used to work some time ago.
The OS is Win7.

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} --- unit Unit1; {$mode objfpc}{$H+} interface uses Classes, SysUtils, Forms, Controls, Graphics, Dialogs, StdCtrls, fphttpclient, opensslsockets; type { TForm1 } TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private public end; var Form1: TForm1; implementation {$R *.lfm} function HTTPTest: Boolean;var HttpClient: TFPHTTPClient;begin HttpClient := TFPHTTPClient.Create(NIL); HttpClient.AllowRedirect := True; HttpClient.HTTPMethod('HEAD', 'https://github.com/bgrabitmap/lazpaint/releases/download/v7.2.2/lazpaint7.2.2_setup_win32_win64.exe', NIL, []); HttpClient.Free;end; procedure TForm1.Button1Click(Sender: TObject);begin HTTPTest;end; end.

probably a ssl related issue. Have you installed the correct dll's ?

CM630:
I have installed no drivers. I have no idea what SSL is. fphttpclient requires opensslsockets, that is why I have added it in the Uses section.
I am trying to find out why s.o. elses code stopped working for me.

ssl is a security protocol used to access websites.

the unit opensslsockets loads the corresponding dll's for you in order to make use of that for your connection.

However, win7 is very old and i doubt it has installed up to date opensll libraries.

see for example this thread (there are many more so I suggest to do a search).

CM630:
So fphttpclient requires ssl libraries :(
I tried the same code it in Linux Mint, latest version.
I have got the following exception:
Could not initialize OpenSSL library.

Maybe there is way to download files from the internet without installing additional stuff?
