Last comment here. I found the problem and the solution.
Problem: Centos 8 firewall
Best Solution: add the docker networks/interfaces to a trusted zone.
In the host:
1: Find the network interfaces used by docker - run the command:
nmcli
and will show all network interfaces in the computer. The docker interfaces are: docker0 and br-xxxxxxxx (i think that depends on how many networks you have in the cluster)
For me, was 3 networks.
2- Add all interfaces to trusted zone with the command:
firewall-cmd --zone=trusted --change-interface=docker0 --permanent
firewall-cmd --zone=trusted --change-interface=brxxxxx --permanent
firewall-cmd --zone=trusted --change-interface=bryyyyy --permanent
3- Reload the firewall with the command:
firewall-cmd --reload
And will work 
If you want to test if the problem is the firewall or not you can disable the all the firewall with:
systemctl disable firewalld
But you need to restart the host (centos8) after that!!! If you don’t restar, will not work!!!
I lost days in this, good luck for everyone who land here!!
