hello community

i wanted to setup a second masternode, but is is not working.
i choosed this guide to setup the first and second mn: https://github.com/Realbityoda/Carebitcoin
they are run on different server with different ip.
if i try to start the MN2 it showes me "enabled" on the status. but if i check it on the server with this command: arebitcoin-cli masternode status, it says the mn is not in the mn-list. after same hours the status changed to "missing"
i really have no idea what could be wrong.. do you have a idea?
thanks a lot :-)
