solutions for?

Hey everyone! Just a small update, we are still investigating this error. We have a couple suggestions up in the sticky post (forums.xbox.com/.../156953.aspx)
and we'd like to keep this conversation there. Thanks!

Hello Empereurjc98414,

Thank you for posting here on the Xbox forums. We understand that you are not able to access the auction room in Forza horizon 4. Are you getting any error code or message? If you haven't already, we also recommend getting in touch with the developers for
support, since that is an in-game feature.

Hi, thanks for responding

-It is a regular Xbox One S

-There are no other external devices plugged into my device

-Yes, it says "No signal" on my TV when I turn the Xbox on

-Due to the way my TV is postioned. I am unable to fully removed my HDMI and use another HDMI cable or a different port on my TV

Or you could find a simple guide at portforward.com , find your router, skip the ad by clicking the right hand corner, and select xbox live 360. It'll give you a walk through on port forwarding.

Ports

53 TCP/UDP

80 TCP

88 UDP

3074 TCP/UDP

Also, if you turn port forward, you need to make sure to have UPnP turned off or it won't work.

I would suggest trying to login on xbox.com, there it will say if it's an invalid user ID or invalid password that you are entering. This is kinda why that code comes up. If it's coming up with invalid ID give 18004MYXBOX and you can get the correct Windows
Live ID that is associated with your gamertag. If you have the ID and not the right password you'll have to head over to account.live.com and reset the password there.I've been told it can be with an error with the WLID so I'd try to login on account.live.com
as well. I hope this helps. Also make sure to delete then re-download your gamertag to the console first just to make sure that won't fix it! Good luck!
