Unknown (Enabled) - Node address service checking is enabled, but result is not available yet

Hi team good day

could someone help me, I'm trying to configure the device (F5), but when I add the nodes I get the following message: "Unknown (Enabled) - Node address service checking is enabled, but result is not available yet"

The  thing is that when I access via cli (ssh) and execute a telnet to the port it is successful, but the service is in a blue state. 

I send screenshots of the error:

Could you help me please, it's the first time I've configured it, thank you:

 

 

successful connection telnet to port 7500 via cli (ssh):

echo "" | nc -v -w 1 10.154.104.6 7500
Ncat: Version 6.40 ( http://nmap.org/ncat )

    Your F5 BIG-IP is in a forced offline state. So no health checks 😉

    In BIG-IP 11.5.3, 11.6.0 HF6, 12.0.0 and later, the bigd process does not send monitor traffic to pool members and nodes when the system is offline and does not update the state of the monitored objects. This results in the following behavior:

    • When the BIG-IP system starts with Force Offline enabled, monitored nodes and pool members are initially marked Unchecked, then remain Unchecked until Force Offline is released.
