Reporting in CQ

The compreport is being used in our application. In my local, I can access it, view the report with all the generated details perfectly. Whereas when it is being accessed from higher environments such as dev and qa, it opens, sidekick is displayed, page layout is displayed, but nothing else happens. There is no sign of a process going on. I checked the permissions for the users and everything is enabled. There is no additional customization done to the component. Please let me know in case of any solutions to this. Thanks in advance!
