this page cannot be displayed in IE 10 or any other browsers?

Hi,

I have this error in IE 10 : -

"This page can't be displayed

•Make sure the web address https://intranet.gebiz.gov.sg is correct.
•Look for the page with your search engine.
•Refresh the page in a few minutes.
•Make sure TLS and SSL protocols are enabled. Go to Tools > Internet Options > Advanced > Settings > Security "

there's no problem with my internet connection... I can access other pages, be it https or http.. I just cannot access this particular website in IE or in other browsers on my laptop... others can access to the website but not me... nothing is wrong with the TLS or SSL protocols... It has been enabled... no compatibility issues either... so what exactly is wrong?

thank you...
