About F5 idle timeout and keep-alive

Hello experts,

 

We recently had a service where the connection would be interrupted before the idle timeout ended.

Idle timeout is set to 5 minutes but the connection cuts out after about 1 minute 

After testing, everything is fine after bypassing F5.

---

Then we set the TCP Keep Alive Interval and it works fine...

 

Why is this happening...?
