Playfab build can not start Fusion session

Hi, I'm currently working on a project that using Fusion on Playfab server. I modified Fusion Asteroid into a Server Client game, my server can run locally in headless mode(using Dedicated Server build option in Unity 2021.2.0).

But when I deploy the build to Playfab, the server instance can not start Fusion. I try to put PUN2 lobby function into the OnServerActive() method and PUN2 work fine, it can create room and see the room on the client, but Fusion doesn't

Can you guy point out where I'm wrong

I use PUN2 and Fusion at the same time to test if the error comes from Playfab but it doesn't, PUN2 work fine

Thanks
