Are you sure your URL is valid/can be accessed by telegram from the web? I cant access it myself — Jemar Jones

So the url you're using in your code that gives you that error message, is actually 185.126.201.42/iisstart.png? — Jemar Jones

The problem can be originated from the following issues:

the image file extension is not allowed by the telegram.
file size is larger than that allowed by the telegram.

You can start with the former one.

Accoding to example you can sendPhoto:

await Bot.SendChatActionAsync(message.Chat.Id, ChatAction.UploadPhoto);

            const string file = @"<FilePath>";

            var fileName = file.Split('\\').Last();

            using (var fileStream = new FileStream(file, FileMode.Open, FileAccess.Read, FileShare.Read))
            {
                var fts = new FileToSend(fileName, fileStream);

                await Bot.SendPhotoAsync(message.Chat.Id, fts, "Nice Picture");
            }
