Dedicated Server for RTS

I looked for a bit on the forum, but I didn't find a fitting answer.
I'm not sure what photon product to use / I don't even know if Photon provides this sort of solution.

I want to create an RTS with a dedicated server.
As I saw in this video there are no good solutions.
And some people in a discord server really recommend me to write my own server.

What's the current state to this topic?
