Unable to log-in to aggregate page

1. What is the problem? Be very detailed.
We have been using the server 'https://csd.icar.gov.in/ODKAggregate/' in India for years. Since yesterday, we are unable to login. The page not showing anything after we enter credentials - doesn't move at all.
2. What app or server are you using and on what device and operating system? Include version numbers.
It's of google.
3. What you have you tried to fix the problem?
First time encountering this issue. Have done nothing so far.
4. What steps can we take to reproduce the problem?
Please advise a solution or reason - why we are facing this. Did people face similar issue elsewhere anytime in the past?
5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
No other information, i can provide right now. But, will get back to our IT team soon to know more.

it's difficult to tell what's wrong... do you get any error or something?
