Several Dreamweaver features require Internet connectivity. If you or your organization is routing Internet connections through a proxy server, you must provide the server credentials for Dreamweaver to connect to the Internet successfully.
You can specify the proxy server credentials in the Adobe Creative Cloud for desktop app. When the Creative Cloud desktop app is first launched, it determines whether or not the Internet connections are routed through a proxy server. If a proxy server is set up, it prompts you to provide the credentials. If the Creative Cloud desktop app is already installed and the proxy server is then set up at a later point in time, then too, the app detects the proxy server automatically and prompts for credentials:
When Dreamweaver queries for a connection to the Internet, it will recognize that the credentials have already been set and stored in the Creative Cloud desktop app and leverages them.
If you are an enterprise customer and the installation does not include the Creative Cloud desktop app, you will be prompted by Dreamweaver to provide proxy server credentials:
Contact your system administrator if you need assistance with the proxy server credentials.
