Your browser might have some hard time to run the anti bot javascript verification code, the ?i=1 behind your url means the verification is successfully and it will allow you to access the website, you can check out the knowledge base for more infomation, usually other user can access your site normally, they wont facing that problem
I just checked your website using a fresh Chrome browser window (a new guest mode window), and the website worked fine without any issues. The video background takes a few seconds to download (it’s a pretty big file), but everything is snappy besides that.
I don’t know why it’s not working properly for you, because there is no problem with your website as far as I can tell.
