[Photon Bolt] Cannot create room in sample project.

I integrate bolt into my unity project via assetstore and I try to run some sample projects for tutorial learning.
I set up an bolt app on the web dashborad and opened the official 'SimpleMoveAndShot' scene.
After clicking the 'Start Server' I successfully connected to the lobby.
But when I started room creating, it got stucked for 20 seconds and finally poped a 'time out' warning.
I searched a lot in the documentation and could not figure it out.
Is there anything I missed?

It seems bolt was a legacy package and they provide a new sdk called Fusion now.
For anyone troubled, you'd better switch to the new solution instead of bolt.
