Errors: [113] no route to host AND [111] connection refused

I have these errors with server and agent, I installed them on 2 virtual machines, and I set connection to bridged.

My server machine ip address: 10.166.88.63
My agent machine ip address: 10.166.88.89

Here are my configuration files:

Problems fixed

The "no route to host" was a firewall problem, I simply executed this command on both server and agent machines:

#systemctl stop firewalld.service

and for the other problem, it was just some wrong ip addresses.
