Rediff.com India — Error in fetching mails

I am not able to access mails from my rediffmail account since last week. At first I am not able to login to account as it takes too much time and fails login saying " The Connection has timed out" I tried shutting down firewall but didn't work.
If I get in acccount, on clicking mail subject it shows " Error in fetching mails. Try again later."
On android mobile and tablet, I am facing the same problem. I can access gmail but cant rediffmail. Please, help me as I have important mails to address.
Thank you
