Hi I cannot connect a cluster with a rancher server 2.8 The error I am getting in the rancher agent is

time="2024-01-17T01:13:20Z" level=info msg="Connecting to proxy" url="<wss://desa-rancher.xxx.cl/v3/connect/register>"
time="2024-01-17T01:13:30Z" level=error msg="Failed to connect to proxy. Empty dialer response" error="dial tcp: lookup desa-rancher.xxx.cl: i/o timeout"
time="2024-01-17T01:13:30Z" level=error msg="Remotedialer proxy error" error="dial tcp: lookup desa-rancher.xxx.cl: i/o timeout"

However I did a successful connection for wss with curl between the servers, so seems to be something else.
