Please use Apple's support document Track your sleep on Apple Watch and use Sleep on iPhone - Apple Support as a checklist. If that doesn't help it is also a good resource to identify each step when describing more detail about how it fails.
Also, on your iPhone go to the Health app and locate Sleep. Scroll to the very bottom of the Sleep page and check relevant items like Data Sources. You can also view the raw data to see if anything is even being recorded for your sleep times.
