Cristianoti, this error occurs because the computer is being blocked from contacting our servers. I see that you also attempted to contact our chat support, but were unexpectedly disconnected both times.
If you are familiar with how to manage your network, then please verify you are able to access the servers and ports listed in https://helpx.adobe.com/enterprise/kb/network-endpoints.html. If you are unsure of how to make these configuration changes, then please contact our support team at https://helpx.adobe.com/contact.html for assistance. You will need to use a different computer, smartphone, or tablet if you are incapable of maintaining a stable chat session.
