Hi Udid, Thanks for your help. However, it has happened again. This time, i realised the blue screen freeze has happened, after i deleted the default users from Jaspersoft. The console is showing no error. However, the HTML has not loaded any content in <body> tag. It looks like the json response from AWS has incomplete html code. Please let me know how to solve this. I dont want to restart the CloudFormation again. thanks.
