DeepAR license key issue

I am facing an issue with the DeepAR license key. I have followed the DeepAR WebApp documentation for setting up a new project and creating an SDK Key. After deploying the web app on a hosting server, it throws a license invalidity error after getting camera permission. Even I generated my license key by putting my domain. You can access the web app here: I have also attached a reference screenshot for you.

  1. License key is set in the code and matches my app id
  2. After showing an alert of an invalid license on firefox it is working fine but on chrome and safari browsers webpage is not responding

Can you please specify a solution to this issue?
