[HTTPS] begin...
[HTTPS] POST...
[HTTPS] POST... failed, error: connection refused
Other than ssis and password, is there anything else that needs changing?
To double check I copied and pasted the code from this thread into the Arduino IDE then put in my SSID and password. The sketch connected and posted 2 variables.
From a web browser does connecting to https://posttestserver.com work? If so, check the server cert SHA1 fingerprint. It must match the fingerprint shown below.
http.begin("https://posttestserver.com/post.php", "2E:FA:E4:F8:6D:8A:DE:4C:CE:07:9C:B8:22:08:AB:8F:B9:F8:8D:6D");
I made 100% sure that my SSID and Password is correct. I successfully connect to the network but it keep telling me unable to Connect when it gets to the post part of the data.
this is what i get in the Serial window:
[HTTPS] begin...
[HTTPS] POST...
[HTTPS] POST... failed, error: connection refused
I also took the data and posted it through fiddler(Composer) as per below :
and it successfully returned a 200 What could be the problem?
POST https://posttestserver.com/post.php HTTP/1.1
