question

I have a spare Cerbo that I use for testing and it works fine at home can access remotely, so I thought I would try it out on site, where we have two systems both off grid one uses the colour control GX and that works fine, I do remember setting that up at the workshop first and Remote console worked and also worked on site, it is currently connected through a EE mobile 5G/4G router via a wifi access point, the other which is the new install and new EE 5/4G router Cerbo connected on LAN also tried WAN and WiFi, this is the one I cannot connect to via remote console. I can view it remotely on the VRM Dashboard and see all other functions. It is logging data so it is connected to the internet.. Any way thought I would take my test Cerbo to site and see if that would connect via router and to my surprise it would not connect the remote console I have not changed any settings just moved location and plugged an ethernet cable tried both WAL & LAN and WiFi, so then I tried the other older system on the same site but through an older EE 4G router, still same problem No remote console, remote support IP address still at zero 0 found in General, Now frustrated took it back home re connected it and low and behold remote support IP address was allocated, all I have done is power down move it,

Remote console is required as you can't get to all the setting in the VRM.

I was wondering as the only thing that has changed is the location and does that prevent remote access?

Any further guidance would be very appreciated
