Growatt USB datalogger firmware problem

Hello all,

I recently upgraded my datalogger firmware via server.growatt.com. All successful, but strangely enough the S/N changed to 0000000000 and this is also the hotspot name it creates. I can see that it is successfully connected to my WiFi and light has a slow blue flash. Problem is that in the ShineWiFi app it shows the signal as excellent, but the connection as lost. Factory reset has not helped. Should I upgrade inverter firmware as well?

Anybody ever seen this issue?
