have easy solar running for 7 days but each time I login to vrm there is no history since 10 days ago and no connection. Is lan internet connection necessary for vrm. As I did get some problems with a loose Ethernet cable. I can get virtual remote but not vrm. It is an EasySolar gx2 with 250/70 48volt 2 pylontech 2000c and an et112 as a power meter
