 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. Note that, even when configured to use plain HTTP, some outgoing requests will always use HTTPS on port 443.
 Firmware updates:
-  * The CCGX connects to [[https://updates.victronenergy.com/|http://updates.victronenergy.com/]] on port 443.
+  * The CCGX connects to [[https://updates.victronenergy.com/|https://updates.victronenergy.com/]] on port 443.
 Remote support (default disabled):
-  * When enabled, an outbound SSH connection to supporthost.victronenergy.com is maintained. The CCGX will try to connect on port 22, 80 and 443, and the first that works is maintained.
+  * When enabled, an outbound SSH connection to supporthosts.victronenergy.com is maintained. The CCGX will try to connect on port 22, 80 and 443, and the first that works is maintained.
   * Enabling Remote Support also enables the sshd daemon, listening for incoming SSH requests on port 22. See next FAQ entry for more information about the Remote Support functionality.

 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.
-  * See [[vrm_portal:troubleshooting_ccgx_vrm_connectivity#trouble_shooting_remote_console_on_vrm|here]] to trouble shoot Remote Console on VRM.
+  * Remote console also relies on the data connection to the VRM portal using HTTPS (port 443), as describe above.
+  * For troubleshooting, refer to the [[https://www.victronenergy.com/live/ccgx:start#remote_console_on_vrm_-_trouble_shooting|Remote Console on VRM trouble shooting guide]].
 Remote Console on LAN (default disabled):
