Hi Nguyen,
Do you see any other problematic symptoms such as:
- S-TAP is restarting, or crashing
 
- S-TAP is receiving too much traffic (priority queue is changing, buffer overflow is happening)
 
- Network between the S-TAP and the appliance is unstable
 
If you don't know, I'd suggest to open a support ticket and send Win S-TAP Must Gather, so that an assigned support engineer will review the Must Gather output.

Subject: S-TAP Control not displayed
Hello everyone !
I am having an issue where I installed S-TAP on a Windows server, but it is currently not showing up in S-TAP Control. I checked the logs from the Stap.ctl file and it shows that it cannot connect, reporting:
