Hi! I typed "masternode start" at the debug console, the following sentences appeared. "Not capable masternode: Can not detect valid external address. Make sure to use IPv4 address only." What should I do?
In vivo.conf add: externalip=[your external ip address]
If you're doing this at home and not on a VPS you also need to open port 12845 on your router and point it at your internal PC so that inbound traffic can get to your node.
