how do I register a player on my self hosted server?

[fahadshery]

Hi,

I just got my pisignage server up and running using docker.
I have imaged the respberry pi 5 as well as a player.

But in the server Web UI, I can't see the option to add this player and register it with my self hosted server:

What am I doing wrong?

Hi,

In open source server, when you point the player server name to http://:3000, it is automatically added.

I had the same problem, and this help page helped me to solve it.
It was network issue in my case. I hope it helps someone as it helped me.
