NETPLAY: Black Screen (Dont works)

[ToastMan]

Hello!
I trying to make work Netplay, i have the same rom, same hash, same core and all.
But when i try to enter i get black screen for a coulple of minutes then says "Failed Netplay" and backs to the home screen.
What im doing wrong?

I have the same games and system and all, i just clones my sd, and put it in another Raspberry.

Do you hash roms ?

With recalbox player ?

@acris

I hash all roms
RPi3
When i host, i cant i get this error
When i try to connect to another Host, i get the same error
Recalbox Player with the Last Version. (Same Roms - Same Core - Same Hash) (I made a cloned image, to have all the same things configured)

I have all games scrapped, i need to do that again?

Check if your internet-router has UPNP activated and/or the appropriate ports opened/forwarded.

This is my Router Config. Its enabled.

Use this tool, to check, if Netplay TCP Port (should usually be 55435, if I'm not mistaken) is open:
