error message :
failed to resolve public ip. retrying...
public ip resolution is just a curl pull to
https://icanhazip.com/try it by hand and see if you get any useful info
curl https://icanhazip.com/
And, you're welcome!
In USA server I can ping icanhazip.com
dfw.icanhazip.com 104.238.145.30
But in my country local Mn can't ping icanhazip.com
I doubt it's a country thing (although I could be wrong)
It sounds more like a firewall thing.
Can you ping 8.8.8.8 from that masternode? (test icmp protocol in/out allowed)
Can you retrieve another ssl page such as
https://google.com/ ? (test port 433 out allowed)
