I have a Growatt SPF5000ES inverter with 2x Pylontech UP5000 batteries. My datalogger lost connection with the server after 11:20 yesterday yet it is connected to the internet, flashing green light. Deleted the datalogger and re-add. Still no connection to the server. Setup connection to a different wi-fi, no connection to the server. Retried home wi-fi and still no connection to the server. Any advise on how to resolve this issue?
