Victron energy Venus GX Manual page 61

Please be careful with enabling this feature on ESS systems: when grid connection is lost, and the GX
device reboots, the system can loose power when rebooting takes too long (when grid is present, the
Multi's or Quattro's will enter passthru)
5.4 Trouble shooting data logging
This chapter explains what to do when the GX Device cannot transmit data to the VRM Portal.
The communication required to send logs to the VRM Portal is:
1. Working DNS
2. Proper IP address
3. Working internet connection
4. Outbound http(s) connection to on port 80 and 443. Note that should never be an issue, unless
on very specialized company networks.
Note that the CCGX does not support a proxy setup.
Step 1: Update the GX Device to the latest available firmware
GX Device firmware update instructions
Step 2: Verify the network and internet connection
In the menu Settings → Ethernet or Settings → Wi-Fi, check the following:
1. State must be 'Connected'
2. There must be an IP address, that does not start with 169.
3. There must be a gateway
4. There must be DNS servers
For a GX GSM, see the Troubleshooting guide in the GX GSM Menu.
In case the IP address starts with 169, check whether your network has a DHCP server running. 99%of
all networks have a DHCP server running and it is enabled by default on all well-known ADSL, cable
and 3G routers. If there is no DHCP server running, then configure the ip address manually.
