Reason : This happens when your network's firewall is blocking access to your EthosData Dataroom(https://dataroom.ethosdata.com)
Solution: Please request your IT team to make sure that your firewall set up allows access on ports 80 (http) and 443 (https). Also, ensure that there are no restriction applied to *ethosdata.com (ie. https://dataroom.ethosdata.com) and the DRM is able to connect to our policy server on https://ps.ethosdata.com/ps1 through the firewall/proxy (and is not blocked).
Once these changes are done, try entering the URL again and you should be able to access your Project.
