I have forwarded your problem to the developers. Meanwhile, I'd recommend you to turn off proxy and VPN or try another browser \ another device. We would be really greatful, if you can contact our support via live chat on our website if you experience the same problem again.
currently i don't use any Proxy or VPN to visit the website but i just use google chrome browser to visit the website and right now it still not working.
Then i try to use another browser like Microsoft Edge and it works perfectly.
