Er706w v1.0 failed to reconnect to Remote controller after each power fail
My cabin is running some network with solar panel and battery.
In darker day of winter I must shut down the power when i'm off site to save the battery.
Last winter, everytime I power up the system, everything work as usual perfectly.
This winter each time I power up the system, the Er706w and some other device stay disconnected from remote Omada controller (home)
The VPN (wireguard) don't come up so cabin is completly isolated from remote control (2 hours car drive)
The cabin network use Starlink as provider
The only way to reconnect the Er706 is to reset it and readopt it with the controller, doing this made configuration come back and other device automaticly reappear connected to the controller. Not very usefull for my wife and guest.
The power of the cabin Been on a timer in the winter for monitoring heating and battery, this problem cause lot of trouble managing the cabin. Adding time consuming to reconfigring it. The system is presently unreliable.
Firmware has been updated since last winter (firmware problem) , the system work flawless until this new winter
I joined the screenshot of the controller (cabin Site)
My best regards
Thank you

Answer 1: Controlller ver: 6.0.0.25 in virtual linux machine running under proxmox, The port for the controller (ip 192.168.27.233) are forwarded to public IP, 
Answer 2: Home (main) topology; the gateway is a ER707-M2 v1.0, firmware 1.3.1 Build 20251009 Rel.67687
Topology of the cabin: The router ER706W v1.0 firmware 1.2.2 Build 20250821 Rel.60581 receive the IP from starlink (Starlink is in Bypass mode like a nomal provider)
Answer 3: When the cabin gateway boot normaly, it reach the controler on the public IP of home network. It also built up a VPN a birectionnal Wiregard connection to home Gateway. The home is the server and the cabin is the client. (note those part work flawless when the Cabin gateway boot normaly)

Home peers
Answer 4: Some part of the internet work at the cabin because some client connect but other not., Some device also connect to the controller wired and wireless but not the gateway. Gateway, switch and bridge stay offlinebut All AP reconnect to the controller at the power up.
Last winter never a power up cause this probleme (same hardware)
What I change: Cabin gateway firmware, controler version, and maybe the home gateway firmware
For the LEdstatus , I will not be at the cabin until next weeks, the Power come on from 10h00am to 10h30 am
I think the problem is really in the firmware of the ER706W v1.0 (maybe a DNS issue at boot)

I confirm then some other device are not connected to the controller.
I don't explicitly report that because last time I reset the Er706 W and readopt it in the controller, everything come up normaly and very fast. So in my view the only problem is the gateway. But next power cut, the problem come back.
Adding some detail about device (both switch are in accessory building at the cabin and are connected to EAP one in shed and the other in boathouse). wired client of switch don't have internet, I believe then the lan port of the switch don't have network. The wifi Still work.
Here I make some annotation in the topology
I will not be at the cabin until few day, so lot of testing will be hard to do until then.
Also, one of my easy test will be to roll back firmware of the Er706 to the one used last winter. I need to do that when i'm at the cabin for few day.
I will follow this part of the test here.
All other test will be by the ticket opened for my problem.
My best regards
