PC behind Powerline Adapter cannot connect to server in my home

[wonnebauer.salkinxd]

Hi,
my PC is behind a Powerline Adapter which is connected to the Router and my server is directly connected to my router. The problem is, when I use ssh from my PC to connect to my server, it times out. But when I do it from Terminus on my Phone it works.
I've heard that Powerline Adapters create some kind of "subnetwork".
Is there any kind of workaround to this, so I can access my server from my PC?

The server is orignially supposed to be a NAS server, just for some context.

ARP on my PC says there is no 10.0.0.42 (my server)
what should I do?

What IP address does the PC have? Is it a 10.0.0.x address also? Is the default gateway set to the router IP address (probably 10.0.0.1)?

So my PC and my server both have 10.0.0.xx addresses.
My router has this IP: 10.0.0.138

Where do I set the default gateway? Does it reset the ssh access that I do have with my phone?

If your PC is set to DHCP then the default gateway is usually set automatically. Open a cmd.exe window and run "ipconfig /all" it will show your default gateway address.

Since you can't ssh, I assume you have attempted PING and failed?

The default Gateway, DHCP Server, and DNS Server are all the same IP 10.0.0.138
I have attempted a PING but it didn't time out, it just said "Destination host unreachable"

Can you ping the router? If you can ping the router, then it isn't powerline network problems, it is probably something on the server side.

So I found out that I set my PC as a DMZ and I didn't remember it. I disabled it but the problem is only half fixed.
I can access my PC via ssh now, but if I use it as a game server or NAS it still doesn't work.
I checked if the ports are open, and they are. So I don't really see the problem.
I tried to connect to my game server via external and internal IP, neither worked.

I can PING my router without a problem. I can now also PING my server.
