Hi  Bro,

Pls try to use other network connection to connect the exam.
I was same problem found in my office network(WiFi or LAN), than I try to share the WiFi form my mobile or back to home to using home's WiFi, there is no problem.
I guess some TCP or Port  is blocked from company firewall.

Pls try again by other network connection, hope you can successful & pass the Exam.
   
Is this answer helpful?

Thanks all of suggestion.  I had failed to access HOL by Feb 10, 11 and 12.
And same happened after clear all cookies, change IP, configure lower privacy level in browser, change browser types, disable firewall and anti-virus sw,, use mobile and laptop, connect company and home network.

Finally, Feb 13 can access HOL without do anything,
Then, today Feb 14 I cannot access the HOL page again by using laptop (home network) and mobile (mobile network).

I'm wondering the issue caused by my side?
