Hey luiz claudio , I'm sorry to hear about this issue.
The error you've sent us indicates that Enscape could not connect to our Asset Library server.
Provided that you've had access to the internet at the time this issue occurred, I assume that you probably connect to the internet via a proxy server?
In that case, you'll might need to configure your proxy settings. You can do that in Enscape by clicking the [About] button in the Enscape ribbon -> [Configure Proxy].
Please ask your administrator what to fill into these fields.
If, however, you're not connected to a proxy server, another possibility is that your firewall is blocking Enscape from connecting to our Asset Library server. Please set the following URL exceptions, that are for connection to the Enscape Asset Library, Web Standalone, Panoramas, and Feedback services, to listen on port ‘443‘ with protocol set to TCP (http and https):
Please let me know if this issue continues to persist afterward!
