GSTR 9 for 2018-2019 is not being generated

The annual return GSTR9 for 2018-2019 is due on March 31,2019, and to prevent last minute rush, the domain investor wanted to start working on it early
On 18 February 2019 in the morning at around 7.50 am, the section is greyed out and it was giving the following message
System computed summary is in progress. Please check after some time.

On 19 February 2019, the domain investor checked the GST website again at around 9.45 pm and it is still giving the message
System computed summary is in progress. Please check after some time.

Is anyone else facing the same problem.
