I also have trouble to run my Masternodes. The QT tells me that my MN has successfully started and I also can see it in the Nucleus list BUT the timer doesn't count and my MN disappear after an hour, a typical behavior of MNs when they cannot connect.

The Neutrond on my VPS is up and running, the conf is located at ~/.Neutron/Neutron.conf
it contains the following:

rpcallowip=127.0.0.1
rpcuser=myuser
rpcpassword=mypassword
server=1
listen=1
port=9999
masternode=1
masternodeaddr=My VPS IP:9999
masternodeprivkey=My Masternode PrivKey
addnode=45.63.18.161:9999
addnode=174.59.176.134:9999
addnode=74.120.130.50:9999

My Local neutron.conf in roaming contains the following:

rpcuser=myuser
rpcpassword=mypassword
rpcallowip=127.0.0.1
rpcport=9999
port=9999
server=1
listen=1
maxconnections=56
disablereportupdate=1
addnode=45.63.18.161:9999
addnode=174.59.176.134:9999
addnode=74.120.130.50:9999

I guess there is something missing in one of the confs or I set up something wrong.

Please let me know what it is and how you guys set up your MNs
