I just read the manual on github to run a masternode.
Is it correct that you have to send 200k coins to the wallet on the masternode server and not keep them locked in the local wallet ?
I run a couple of other masternodes and they just lock the coins in the local wallet/generate a masternode privatekey for the server.
This is my issue as well, I'm still trying to run a cold/hot setup with separate wallets: one on the server or VPS and the control wallet on my desktop.
I'll give it a few more days and if it still doesn't work, I'm going to try something on my home server (where I retain full control of the VM / VPS) and see if that works.
For all of those running masternodes and sending the coins to the wallet address that is on the VPS itself, I advice you to export the private key and back it up. If the VPS ever goes down for any reason, if you forget to pay the bill, if the provider does not keep backups, and the instance is wiped or destroyed, there goes your coins.
