Hi Mike757 Mohamed_Ahmed_Kansoh 

Thank you for the reply , We have tried belo steps 

On f5-lan-primary : Did a failover and made f5-lan-secondry as active .

1.Restarted the F5 from CLI - No luck 

2.Restarted the F5 from VM console - issue got resolved .

But strange , why the first reboot from F5 cli did not fix the issue . We hve cse open with F5 support waiting for RCA .

Hi Blue_whale , 

Restarting services differs from Rebooting the Full VM which you restart F5 Kernel and Whole Daemons. 

But I would like to Know the Reason from F5 support team. 
so update us when you know about it.
