To correctly configure the proxy settings for Phonehome and Remote Assist on a FlashArray, the Implementation Engineer requires the Protocol prefix (HTTP/HTTPS) and the Port number in addition to the IP address.
The Purity operating system requires a complete URL structure to establish a connection through a proxy server. A raw IP address like "10.24.18.120" is insufficient because the array does not know which communication protocol to use or which listening port the proxy server is monitoring.
Correct Format: The required input format is typically scheme://host:port. For example, https://10.24.18.120:8080 or http://10.24.18.120:3128.
Why it's critical: Without the port, the connection will likely time out or be rejected. Without the protocol (http vs. https), the handshake may fail. While credentials (username/password) might be required if the proxy enforces authentication, they are optional depending on the customer's network policy. However, the port and protocol are always technically mandatory to form a valid network socket connection.
