Quick answer

A flashing blue LED on an eero means it is searching for an Internet connection: during first setup it waits for the eero app over Bluetooth. If it appears after a reset, check the modem and its cable and restart it for 30 seconds.

Safety first

Stop and check this first

During first setup flashing blue is normal: it means the eero is ready to pair with the app.

Safe checks you can perform

If this is first setup: use the eero app
Check the modem and the cable to the gateway eero
Restart the modem and reconnect in the app
If Internet works and it stays blue: add it back

What it means

eero explains that a flashing blue LED means the eero is searching for an Internet connection. During initial setup it is broadcasting Bluetooth and ready for the eero app; after a soft reset with no Internet it flashes blue while trying to reconnect, and keeps doing so until the connection is restored. After a hard reset it also stays flashing blue, ready to be set up again. The LED alone never proves the eero is faulty.
