Runtime Agent not visible in Katalon test Ops

I bought a second Katalon Runtime agent licence for my new server.
In KRE node locked licence management, everything seems ok: “2 suscribed licences”, “2 Machine quota”. Names of agents are “srv001” and “srv002”.

When i launch each agent in each machine, no error occurs, but only one appears in “Online agent” in test ops, and i cannot schedule anything on the other one…
