question

Hi. Is connection working to VRM working via main connection only back-up connection doesn't work? Following should be checked for the back-up connection:

12.4. Troubleshooting 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 http://ccgxlogging.victronenergy.com on port 80 and 443. Note that should never be an issue, unless on very specialised company networks.

Note that the Cerbo GX does not support a proxy setup. For more details on the required networking, see the FAQ Q15: What type of networking is used by the Cerbo GX (TCP and UDP ports)?.

Thanks @JaniEronen
I will look in the direction of the Ports.
As my normal VRM Portal works, only my newly tried back-up is not accessing properly.

Hi @Harold did you find a fix for this?

I am trying to do the same to get a quicker response to the control panel than going via VRM.

Following the advice above and in FAQ 15 I have opened ports 22, 80 and 443 to the GX device. It seems then I can contact it using my router's IP address and get further than your screenshot upthread, but after a second or two it fails to connect and gives this display

But I can still contact it satisfactorily on the LAN using its local IP address and also via VRM, is there something else I need to do?

Hi

I did not got any further yet, as I couldn't find out how to add more than one port on my remote connect router settings.

Edit:

Main ports in use are 80 and 81, 81 is used for websockets.

I wouldn't enable 22 (SSH), that is asking for trouble remotely, rather create a vpn if you need to ssh for anything.

Personally I wouldn’t NAT this directly to the internet, it is not exactly a hardened device, and anything on the internet is constantly being port scanned.

Thanks @nickdb, I have now got it working after a bit of experimentation.

Ports 22 and 443 are not necessary so I have closed them, thankyou.

Port 81 needs to be open and it needs to be passthrough. @Guy Stewart (Victron Community Manager) it would be nice if this could be added to the documentation cited upthread.

@Harold if you can set up a port range then you could open 80-81 which should work albeit with minimal security.

Port 80 can however be mapped to something else, which provides a small amount of extra security, I have several other HA devices which have web interfaces on Port 80 but they are mapped to different ports on the WAN so I can reconfigure them remotely.

I would as you say ideally use VPN. My router's instructions say "Download the client utility from http://openvpn.net/index.php/download/community-downloads.html" and install it on the devices where you want to run the VPN client. So how would I install the client on a Multi II GX?
