阿里云服务器https调用腾讯小程序授权接口报错，http可以，防火墙已关闭？

使用阿里云服务器提供腾讯小程序的接口，使用http是可以访问的，切换成https不能访问，于是把防火墙关闭了，可以访问了，唯独调用小程序授权的接口报错了，下面提供代码

string response = HttpHelper.HttpPost("https://api.weixin.qq.com/sns/jscode2session?appid=" + WxConfig.WxOpenAppId + "&secret=" + WxConfig.WxOpenAppSecret + "&js_code="+code+"&grant_type=authorization_code", "");

报错原因
