Solar dongle connection failed

[ctmd]

I have a solar inverter that is connected via lan cable to the router. Worked fine for 3 weeks, now stopped working. Solar manufacture cannot find anything wrong their end with dongle or inverter (swapped both out). All filters are off. Help please.

Good morning,

So my inverter is a Fox Ess H3 (the 3phase one).

@ctmd Thanks for the info. We're you aware of the Fox forum?
