Thanks for updating in! I went ahead and investigated further. I have increased the time out limit and validated your site. I am using a test license by the way. I was successful in validating your site. You can check out my screenshot: http://prntscr.com/fs640e and your site in X > Overview page as well.
Since this is just a test license, you will have to revoke the license and re validate the site using your own license. To do that, please do the following:
1] Please go to X Addons > Overview and revoke the validation (https://s3.amazonaws.com/community-themeco/app/uploads/2016/04/17110514/Capture53.jpg).
2] Please login to your account and revoke the license.
3] After you have revoke the license, you need to re assign the license again to your site using this url: https://www.example.com/. You have to make sure that url you just assign is the same as the one you have in your settings, Settings > General > Site Address
4] Go back to X Addons > Overview again, and insert your license code.
And please review the changes that we made on how you are going to validated your X theme because we made a big change in the process. Please check it out here: https://community.theme.co/kb/product-validation/
Please let us know how it goes.
