Unifi USG3 and UF-AE issues

my setup atm

building a simple unifi network. ISP>USG3>24ptSwtch>CloudKey&Ap. but data is not flowing from the isp to the firewall

Using simplex converter by Unifi (UF-AE) to rj45 to the firewall with no luck. light is solid.

Just wanted to reach out to see if there was anything you fine people might know that could be the issue. I have no experience with bi directional fiber.

What county and what ISP?
