HDFC Bank — I'm not able access net banking services

From 7-Feb-18, I'm not able to use my net banking services in website and even in mobile app
When ever i try to access my account on website the page itself isn't responding its just keep on loading and nothing much.(attached Pic)
I have tried using mobile application too but even there its saying like " unable to access the server.(attached Pic)
Isn't there any end to this ?? there isn't any update from the bank authority in its webpage also for why this is happening
