What I'm doing wrong?

Does a simple ping between both computers work? Do you use a linux distribution which enables a firewall by default on the coordinator pc?

[j-urobles]

Ping and ssh works between both pcs. No firewall. Coordinator up the port. I'm using Ubuntu 22.04.
I try with an exporter inside pc 1 like coordinator and works

Edit: I have tried with wireshark in coordinator and I can see the request from exporter

[Emantor]

But you don't see a reply from the coordinator? Are you sure that there isn't a firewall in play? Your coordinator configuration should be correct and the fact that a localhost connection works shows that the coordinator is running. I don't know why the coordinator wouldn't answer a request besides a firewall dropping it.
