Once i also got the same error and after sending multiple mail to gst supporting team i got fixed it after 30 days.
As per my understanding when trying to find solution people told me that "eventhough i got registered at GST Portal and Got GST Number, a Local Tax Higher Authorized officer has to verify it manually and authorize it in his window. Then only I can Login through the First login window and create a username and password".
Some places it happens very quickly, some places takes the local officer delays around 28 to 30 days.
Hence need to wait patiently. It is what I understood. Any how I got permission to Login after 28 days around.
Any how try to call the customer care help line and also try to mail to the supporting team in the GST Portal.
