I have an issue with Xbox Remote Play on my Series S. Every time I try to connect to my console outside my home network, I get a connection error where my console is found, but my mobile device can't connect to it. I tried everything. I used several guides and opened all necessary ports in my router. While my Xbox gives me a go to use Remote Play, I still get the error. I even tried using a wired connection instead and also turned off private relay, but it still doesn't work. Connecting inside my home network works absolutely fine. Also, a weird thing is that the remote control feature over mobile data works.

Does anyone know a solution for that or am I screwed?

I suck at networking, so take my help with a grain of salt, but some questions come to mind:

What specific error message are you getting?
What NAT type is your Xbox using?
What ports did you open specifically and what type of ports were they?
What brand of router do you use?

These are good starting questions to help troubleshoot. Once you answer these we may be able to help some.

We found your console but can't connect (No error code or something, just this)
Open
The ones recommended by Microsoft themselves https://support.xbox.com/en-GB/help/hardware-network/connect-network/network-ports-used-xbox-live
Telekom Speedport Smart 4 with 5G modem

As I said, my Xbox gives condition green for remote play after the test.

I'm guessing that it's because you are using a 5G Modem as your Internet. You are behind a CG-NAT which can cause all kinds of funky things with streaming outside of your own WiFi.

It's a hybrid router.

Your probably still on a CG-NAT, which means it's not gonna work well.

I'm going to have to agree with @[email protected] unfortunately. You're best bet for next step is probably to contact Xbox support and see if there is anything they can do.

Without seeing anything myself, it sounds like you've done everything correctly on your Xbox and home network's end. Have you tried using a different device for remote play?

I tried it on a iPhone, a iPad and a Windows Laptop.

[–] Jestzer 1 points 1 year ago

What network were they connected to when you tried those devices? Also, I'm assuming it didn't work on those ones, right?

What type of mobile device are you using to try and play?
