Telegram SetWebHook Self Signed Certificate - ssl

Question

I'm Trying to Send a Self Signed Certificate To telegram .
The Configuration will be done through PostMan And My Bot Server is Ok (tests through getUpdates and action call over ssl connection responded successfully).
Here is what i send to telegram :
api.telegram.org/botMY TOKEN/setWebhook?url=MY SWERVER IP:443/api/webhook
and i DO attach the PUBLICKEY.pem as a binary body to the request.
Here is what i get :
{ "ok": true, "result": true, "description": "Webhook was set" }
the problem is when i check the webHook via getWebHookInfo :
{
"ok": true,
"result": {
"url": "94.183.157.125:443/api/webhook",
"has_custom_certificate": false,
"pending_update_count": 5,
"last_error_date": 1476206652,
"last_error_message": "Connection timed out"
}
}
in which the attribute "has_custom_certificate" : false means it did't get my certificate :\
What am i doing wrong here ?
Any alternatives to PostMan ??
One Step Further
I tried the HttpClient as below but it didn't work eighter :\
public string SetWebHook()
{
FileStream paramFileStream = new FileStream(#"E:\PATH.......\YOURPUBLIC.pem", FileMode.Open);
HttpContent fileStreamContent = new StreamContent(paramFileStream);
var response = string.Empty;
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileStreamContent, "Certificate", "YOURPUBLIC.pem");
response = client.PostAsync("https://api.telegram.org/botMYTOKEN/setWebhook?url=MYSERVERIP:443/api/webhook", formData).Result.ToString();
}
return response;
}

You must use curl to upload your certificate (pem)
And
You should use HTTPS:// for your url
