Cant connect H5 lobby service

Hello

I’m trying to connect to either social/ranked/warzone playlists in H5 but I always get the same message “attention, unable to connect to Halo 5 Guardians Lobby Service”

I’ve checked my cords and they’re where they should be and none is loose, my internet is fine and I’ve tried to hard reset my xbox.
Nothing seems to correct this issue.

any tips?

Best regards

Ok so I’ve tried to reinstall the game, but I still get this message.

“Attention unable to connect to halo 5 guardians lobby service”

I just dont understand,as I said before I’m online and all cords are fine but I cant enter any playlist or play halo at all I’m just stuck in the menu.

Please help me?!

Ok so I made a full factory reset of my Xbox one yesterday and was able to play but today I’m having the same problems again.

I’m stuck in the Halo 5 main menu, cant connect to any playlist, same error message “Attention unable to connect to halo 5 guardians lobby service”

My NAT is OPEN
My internet connection is fine
My multiplayer connection is fine

and before my factory reset I also tried to clear my MAC adress, didnt change anything.

Does anyone know what can be the problem here?

OK, I am not sure what you mean by “clear my MAC address”. That is basically the serial number of a network adapter. Your router uses that to bind an IP to a particular device like your Xbox - so basically you have a static internal IP even though in general your internal network uses DHCP to assign IP addresses automatically. While on this topic I want to add that it is a bad idea to set the Xbox itself to a fixed IP while the router is configured to do DHCP - most routers do have a setting where based on the MAC address you can reserve a fixed IP for your Xbox.

Now, when you say factory reset you are actually talking about bringing the Xbox back to the state it was on when you first got it out of the box. That would be pretty drastic since it would wipe out all OS updates as well. Did you try the full reboot?

Based on your description I doubt it is a network issue on your end. The factory reset is strange but if it was a hardware issue that factory reset shouldn’t really change anything there.
