I installed mn on my computer (not using vps) according to the instructions. But in the last step bounced the error like this:
22:34:18

startmasternode alias false mn1
22:34:18

{
"overall": "Successfully started 0 masternodes, failed to start 1, total 1"
"detail": [
{
"alias": "mn1",
"result": "failed",
"error": "Invalid port 0 for masternode VPS_IP: 55442, only 55442 is supported on main-net."
}
]
}
Any ideas can help?
Thanks in advance.
Code:
rpcallowip=127.0.0.1
rpcuser=ANY_LONG_USERNAME
rpcpassword=ANY_LONG_PASSWORD
staking=1
server=1
listen=1
daemon=1
port=55442
masternode=1
masternodeaddr=vps_ip:55442
externalip=vps_ip:55442
masternodeprivkey=PRIVATE_KEY
check this,
you must need at less 2 ip to set up a masternode.one local,other vps or computter
