Calling to HTTPS endpoint failed. SSL certificate issue.

Main problem is because the certificate is self signed and unverfied. Android does not allow visiting such URL.

Basically need to prepare the keystore and create a TrustManager that trust this specific server identity. It's a long code but Ion has support in setting up this.

I'll fix this on my end and send a pull request to you. Meantime you can use IVLE endpoint first. Will update you again.
