Netcode's network manager greyed out completely

I just installed netcode and added a networkmanager to an empty gameobject, and it's greyed out completely. I can't interact with anything. any help appreciated.

 

Did you try the Hello World guide?
https://docs-multiplayer.unity3d.com/netcode/current/tutorials/helloworld

 

yes. the issue is that the networkmanager don't work. i reinstalled netcode, restarted unity, etc. no function.

 

Is there a Unity Transport component on the GameObject with the NetworkManager?

Also, some more context would be helpful: Netcode package version, Unity version, OS.
Any errors in the Console?

 

I has added one and still no success

 

That NetworkManager doesn't look right. As CodeSmile asked what Netcode package and version are you using?

Actually it looks like you're under the Debug tab in the inspector.

 

Yes, just set "Normal" mode instead of "Debug".
