Hello VIVO Folks,
I am having trouble setting up my Masternode. I am on step 8 but when I run the "masternode start" command I get this error.
Not capable masternode: Can't detect valid external address. Please consider using the externalip configuration option if problem persists. Make sure to use IPv4 address only.
What ports need to be opened on the firewall and how do I configure the externalip configuration option that is noted on the error?
Thanks in advance for you help!
