问题
I am trying to set up thingworx composer on a Linux machine.
In the Application logs the Server is ON and db is initialized.
But when in the browser I try to open composer, then it is stuck at the landing page (the black page with Thingworx logo in green) and doesn't go to the Composer Home page.

@Tarun if you are still facing the problem, then try restarting the tomcat and db servers. Make sure that there exists 'Thingworx' folder under Tomcat install dir/webapps folder, as upon successful installation Thingworx will automatically creates a folder over there.
Considering the Thingworx directory exists, try to access the apache tomcat's catalina logs and look for any errors at the End of File.

Have you tried clearing the browser cache? If this is a migration/upgrade, you may have a prior UI cached in your browser and it is conflicting with the version you are currently trying to install.
Additionally, checking the Security Log and Application Log for any warnings or errors may provide more insight into why the server is not loading Composer.
