Error while accessing SAP Web IDE for SAP HANA viz. AWS

Hi, I was trying to access Web IDE for SAP HANA via. AWS and getting this error. 'Authorization request error. There was an error. The request for authorization was Invalid'. i have gone through thread https://archive.sap.com/discussions/thread/3944992 as well which says something about changing URL by adding domain also. Does it say about URL we mention in Host file? Could anybody please help how could i resolve this error. Thank you
