SOLVED! Problems reading info from a Axpert VMIII Twin 4KVA on SolarAssistant

Dear users of this magnificent forum,

I suspect that my COM module could be broken. Solar Assistant cannot show any inverter port since the 10 last hours. THE TWO CABLES WERE THE PROBLEM

Before, there was connection for all the previous life of the inverter, but, since I had to go and there was so much load at night, to prevent to run out of battery, I wanted to stop the inverter. I had to modify the Cut-Off value through WatchPower app, I have been doing that every time I forget something with a huge load and I cannot stop it physically.

Once at home, I re-started the system and everything went well, until a couple of hours later... I saw I had no inverter readings through Solar Assistant.

I tried several times to reconnect, changed the USB cable, pushing disconnect and change buttons... nothing. Before, for a time, I could see AMA... connection listed, but suddenly disappeared forever. I tried to connect via ARJ45 (with a standad net cable) and other USB ports on the Rasperry side, but nothing worked. I have been doing all these steps shutting down several times the Rasp pi and the inverter. It continues doing the same. The good part is I can reach all info and configuration via WatchPower, so, I can understand the WiFi module is working good.

Does anyone know if, somewhere in the configuration, something is erased and needed to be reconfigured? Every time when I do a hard shutdown (and that means to stop everything for a while), I see that the day and time is erased every time and the LCD displays an advert blinking icon.

Thank you so much for your attention
