Question

I have implemented the sigle signon in worpress with Java with Aws cognito.

it is working fine with http but after moving http to https. API's are not working and throwing the error below:

WP_Error Object
(
    [errors] => Array
        (
            [http_request_failed] => Array
                (
                    [0] => cURL error 35: error:1408F10B:SSL routines:ssl3_get_record:wrong version number
                )

        )

      'password' => $_POST['password']
      );
   $response = wp_remote_post('https://example.com:8083/digitalIdentityProvider/login', 
               array(
                  'method' => 'POST',
                  'timeout' => 45,

After playing with wordpress code and AWS, I found the issue with Aws ELB and Load Balancer .

SSL Certificate has applied to LB and Third party API and wordpress were hosted on AWS EC2 and for EC2 there was not SSL certificate and I was trying to access API with HTTPS:

https://example.com:8083/digitalIdentityProvider/login hence request was not verifying over there hence I was not receiving any response from API.

I have changed API call

from https://example.com:8083/digitalIdentityProvider/login

to http://example.com:8083/digitalIdentityProvider/login

after change it https to http. it working fine.
