conn:on("connection",function(conn, payload)
conn:send("HEAD / HTTP/1.1\r\n"..
"Host: https://api.thingspeak.com/apps/thinght ... L7DOCEHHX9\r\n"..
"Accept: */*\r\n"..
"User-Agent: Mozilla/4.0 (compatible; esp8266 Lua;)"..
"\r\n\r\n")
end)
conn:connect(80,184.106.153.149)

Since you are using Lua, it is better to post in the Lua sub-forum ...

Try putting your IP address in quotes, and check if your host listed as HTTPS header is ok since you are using HTTP -- server may reject it.
Also, the conn:on("connect"... I thought had some problem--I could not get it working before..
Not sure if you have been looking at the docs here, but check this out http://nodemcu.readthedocs.org/en/dev/en/
