I zeroed the block chain, erased addnode from .conf e tried to resync ... now the height is 13010 in VPS node . The same in the desktop but height is 13008. I think that blockchain has forked at 13010-1312 and trying to resync drop some blocks. And chains is returned back to POW side and none is mining. What a big mess ... we need devs!
EDIT :I restarted two desktop wallets zer0ing the chain, and saving the wallet e restart mining ...
