 VRM Portal:
-  * Data to the VRM Portal is sent via HTTP POST and GET requests to http://ccgxlogging.victronenergy.com on port 80. Sensitive data is sent using HTTPS on port 443 to the same host.
+  * Data to the VRM Portal is sent via HTTP POST and GET requests to https://ccgxlogging.victronenergy.com on port 443, with a user configurable override to use plain HTTP on port 80. Although even when using port 80, some outgoing requests still use HTTPS on port 443.

 MQTT (default disabled):
-   * When enabled, a local MQTT broker is started, which accepts TCP connections on port 1883. The CCGX will also try to connect to the victron MQTT cloud server (mqtt.victronenergy.com) using SSL on port 8883.
+   * When enabled, a local MQTT broker is started, which accepts TCP connections on port 1883. The CCGX will also try to connect to a victron MQTT cloud server  ranging from mqtt0.victronenergy.com to mqtt127.victronenergy.com), on port 443, using SSL. It uses port 443 to reduce the chance of using blocked outgoing ports.
 Remote Console on VRM (default disabled):
   * Remote Console on VRM uses the same reverse ssh tunnel as is used for Remote Support: outbound connection to supporthosts.victronenergy.com on port 22, 80 or 443. No port forwarding in routers is necessary to use Remote Console on VRM. Note that supporthosts.victronenergy.com resolves to multiple IP addresses: 84.22.108.49 and 84.22.107.120.
+  * Remote console also relies on the data connection to the VRM portal using HTTPS (port 443), as describe above.
   * See [[vrm_portal:troubleshooting_ccgx_vrm_connectivity#trouble_shooting_remote_console_on_vrm|here]] to trouble shoot Remote Console on VRM.
