Arduino: HTTPS POST request to api returns -1 response (ssl)

[rohit-rcrohit7]

I am trying to post a .json message with field "chip_id" and "power" to my https api made. But response error code -1 is coming back, and data is not getting inserted there.
I used this code found and modified the url , wifi credentials ,and thumbprint.
Can someone explain the issue?
(working fine with postman)

Well, the first error your log says is "[begin] failed to parse protocol".
And indeed, the URL you pass to begin does not start with a protocol ("http://"), so begin fails.
After that, connect complains that begin returned an error and so on, so I would suggest you to first fix the url by adding "http://" and retry...

[rohit-rcrohit7]

ok , so I edited my uri , but still http response is -1 , debug message i updated in the original post.
My thumbprint is correct, cross checked it from the certificate(sha1)

[vicnevicne]

Wow, modifying your original code and log along the way is not very good practice because the discussion is now impossible to follow for others.
Anyway, I have zero experience with SSL on ESP, so I'm afraid it's now out of my field.
However, do you have success if using a GET method ? Just to know if it is really POST-related or if you have to look somewhere else...

[rohit-rcrohit7]

I think its something to do with my certificate instead ? code works fine with other api's out there , or with GET i guess, even am very new to this.

@thorburn1 you are lucky that I have been doing some fingerprint stuff in the last few days. After a very minor mod to your sketch Serial Monitor shows:

[HTTP-Client][handleHeaderResponse] RX: 'HTTP/1.1 200 OK'
[HTTP-Client][handleHeaderResponse] RX: 'Date: Fri, 06 Jan 2017 10:52:26 GMT'
[HTTP-Client][handleHeaderResponse] RX: 'Server: Apache/2.2.31 (Amazon)'
[HTTP-Client][handleHeaderResponse] RX: 'X-Powered-By: PHP/5.5.30'

[HTTP-Client][handleHeaderResponse] RX: 'Connection: close'

[HTTP-Client][handleHeaderResponse] RX: ''
[HTTP-Client][handleHeaderResponse] code: 200
[HTTP-Client][handleHeaderResponse] size: 106
http result:200

OK so what's the mod. For some reason you have an invisible character at the start of your fingerprint and when I pulled down your fingerprint from https://www.grc.com/fingerprints.htm it seems to have given me the same. Simply go to the position in your sketch before the first F in the fingerprint and watch as you do a backspace on the keyboard. It will remove the invisible character and you will be good to go.

@pieman64 That solved the problem I was fighting for since like 9 hours , thanks a lot.Never expected such error 💃

it doesnt help if you just changed http to https

Worked like a charm, thanks alot. 💯
