Have you started masternode from your local wallet via "masternode start-alias someAliasHere"?
Hi, thanks for your reply UdjinM6, I haven't reached the point of trying to start the masternode yet which is step 9 I think, I'm still stuck on step 7. There is some problem with sentinel connecting to the daemon or something it seems like.
Can I clarify has the port changed? It used to be 9999 and is now 9998 ? Do I need to reconfigure my firewall ?
I bet the guide just should be slightly updated

@moocowmoo did a LOT of work to put this all together, no wonder if some steps are not quite polished yet

EDIT: same issue, same solution

Appreciate the help guys, but I'm not there yet, will keep going tomorrow. From TaoOfSatoshi guide looks like i need port 9999 after the IP address in dash.conf which I've put back in. Now I'm trying to remote start the masternode using "masternode start-missing " in the local debug console but its not working says "Error: Please enter the wallet passphrase with walletpassphrase first. (code -13)"
