I'm having the same issue for a few hours now. This last time I started my hot wallets while on my first masternode, I thought I'd try dash-cli masternode start on the remote, and it worked, in that it said "masternode started successfully" (usually, all I have to do is dash-cli masternode debug) I did this with both my wallets online after start-many on my local hot wallet. Anyway, doing the same thing with my second MN wallet didn't work. I don't know what's wrong. Local says masternodes started successfully (in the start-many way) but no joy on remote for second wallet.
