This error came up for me as well when I tried to run multiple masternodes on the same VPS. Are you trying to run your second MN when you have this error?
So I tried running the 2nd mn with VPS
You know how to overcome this problem
please guide me.
Do you have 2 IP address on your VPS? If no, you can't start the second mastenode. Arctic don't allow to change port.
I have the 2nd ip
Thank you for your attention
If you know how to get around please patience me
If you have 2 IPs and want to run 2 MN that shouldn't be a problem.
Set up the first masternode using the first IP.
Create a new user with admin rights (sudo)
Log in as the new user and set up the second masternode for the new IP as you have done in the first one (just enter the 2nd IP in the config file)
Another way. Start second wallet with another data files: arcticcoind -datadir=your_second_data_dir
And add to your arcticcoin.conf for second node:
bind=your_second_ip:port
goldminenodeaddr=your_second_ip:port
