HTTPS数据检索错误

Question

我有一个安装了NodeMCU固件的固件（模块：http，tls等）的ESP12。

每当我尝试使用​​使用https连接，我收到以下错误：

> http.get("https://pastebin.com/raw/cAB83eF1", nil, function(code, data) 
>> if (code < 0) then 
>> print("HTTP request failed") 
>> else 
>> print(code, data) 
>> end 
>> end) 
> HTTP client: Disconnected with error: -114 
HTTP client: Connection timeout 
HTTP client: Connection timeout 

在那里，当我尝试没有HTTPS相同pastebin.com链接，我能够接收数据和HTTP状态码。

> http.get("http://pastebin.com/raw/cAB83eF1", nil, function(code, data) 
>> if (code < 0) then 
>> print("HTTP request failed") 
>> else 
>> print(code, data) 
>> end 
>> end) 
> 200 test 

从docs of http.get报价：

Each request method takes a callback which is invoked when the response has been received from the server. The first argument is the status code, which is either a regular HTTP status code, or -1 to denote a DNS, connection or out-of-memory failure, or a timeout (currently at 10 seconds).

由于文档说有效的代码是-1和HTTP代码，我怎么能找出什么是-114？

EDIT1：建设有调试选项上的固件之后。我得到以下错误：

> http.get("https://pastebin.com/raw/cAB83eF1", nil, function(code, data) 
>> if (code < 0) then 
>> print("HTTP request failed") 
>> else 
>> print(code, data) 
>> end 
>> end) 
> client handshake start. 
please start sntp first ! 
please start sntp first ! 
client handshake failed! 
Reason:[-0x7200] 
HTTP client: Disconnected with error: -114 
HTTP client: Connection timeout 
HTTP client: Connection timeout 
=rtctime.get() 
1501394767 272709 
> 

按日志声明Reason:[-0x7200] 0x72十六进制为-114十进制这被后来Disconnected with error: -114打印。

另外sntp.sync()随着从rtctime.get()输出处看到已经被执行。即使SNTP已同步，为什么打印消息please start sntp first !？

而且后来在日志中，在-114消息后，它显示Connection timeout消息。我如何更改https连接的超时时间？任何指向C /头文件的指针？

注：我已经安装了Linux机器上建立固件的git仓库和码头工人的形象。

PS：我需要HTTPS，因为我会做我的ESP12与托管在云中的RESP API通信。
