Error when request to Management API with my custom domain

Hi @ashish,

I’m not calling the Management API endpoint. I mentioned it wrongly in my previous message. I apologize.
Actually I’m trying for access token endpoint with the code parameter (which I received in my callback endpoint).
e.g

Unirest.post(https://${auth_custom_domain}/oauth/token)
                    .header("content-type", "application/x-www-form-urlencoded")                  .body("grant_type=authorization_code&client_id=$authClientId&client_secret=$authClientSecret&code=$authorizationCode&redirect_uri=$redirectUri")

While I’m trying to access /oauth/token endpoint with my custom domain I’m getting SSL handshake certification error. If I use the auth0 domain instead of my custom domain it’s working fine. Is anything need to be configured more?
