Yes. Master Node communicates with port 5000, but with a wrong IP address.

Floating IP give to my instance is in 10.61.61.0/24 but all of my endpoints
are in 10.60.60.0/24, but when I try to curl manual the endpoint with
10.61.61.0/24 it's working fine.
It is possible to change the IP address installed on cloud-init to
10.61.61.X?

Best Regards,
