can not run masternode, what do I do wrong?
Not capable masternode: Could not connect to XX.XX.50.80:9919
Make sure port is not blocked by firewall.
For Linux VPS:
/sbin/iptables -A INPUT -i eth0 -p tcp --dport 9919 -j ACCEPT
I try to adjust on win10. ip must be static or dynamic? or it does not matter?
IP should be static; if you are on the dynamic IP it will work as long as your IP will not change.
If you are on Win10: check your IP address (Google: "whatismyipaddress").
Most probably you are behind router - you will need to open port on your router.
However I would suggest you to run cold MN on VPS - it costs $5 per month and you can run 4-5 masternodes on it ($1 per month per masternode)
