"A certificate is required to complete client authentication" Error during file download using innosetup download plugin

Question

While downloaidng setup files from server using the InnoSetup Download plugin it throws following error:

"A certificate is required to complete client authentication"

My Server where file is hosted supports the TLS1.0,1.1,1.2 protocols. if i try the same url from browser , it works fine. Please let me know the issue.

Code :

idpaddfile(url, ExpandConstant('{tmp}\Setup.exe'));

@MartinPrikryl : Yes.that is our production server where we upload the files for users to download our setup. — Sudhakar Tillapudi, Aug 08 '19 at 12:48
So try to find out why the server requests client certificate for incoming request from your installer. — Martin Prikryl, Aug 08 '19 at 12:54
@MartinPrikryl : when i try to download the file using c#.NET code it downloads successfully! can you please suggest where i have to look into. — Sudhakar Tillapudi, Aug 08 '19 at 13:00
I do not know. But your server is not compatible with [`WinHttpRequest`](https://learn.microsoft.com/en-us/windows/win32/winhttp/winhttprequest) (used internally by IDP). Even a simple code like this does not work with your server: https://stackoverflow.com/q/42805224/850848. When I inspect the traffic between `WinHttpRequest` and your server using Wireshark, it's clear that the server requires the client certificate. — Martin Prikryl, Aug 08 '19 at 13:03
@MartinPrikryl : Okay, Thank you , is there any way to bypass the client certificate? — Sudhakar Tillapudi, Aug 08 '19 at 13:29
How bypass? The server requires it. The client cannot *"bypass"* the request. — Martin Prikryl, Aug 08 '19 at 13:31
@MartinPrikryl : Okay, can you suggest me any better solution now, can i expect any future updates where IDP will work with different method (other than WinHttpRequest) or can you suggest how i can set client certificate usinng innosetup? — Sudhakar Tillapudi, Aug 08 '19 at 13:38
No. IDP will hardly ever be reimplemented. + You cannot set client certificate and I doubt it would help, as I do not really think the server needs it, it just ask for it due to some bug/misconfiguration. — Martin Prikryl, Aug 08 '19 at 13:40
@Martin Prinkryl : Thank you for your suggestion, I will check the server if it is possible to reconfigure.Thank you — Sudhakar Tillapudi, Aug 08 '19 at 13:48
