Hey i am trying to access Xbox Marketplace and i cant…i get 807b01f6 error code. Does anyone else have issues too or i am alone? Please help!
You might want to try contacting Xbox Support. It’s more of a Microsoft error than a Halo one.
It may just be a general Xbox error and nothing to worry about. There is a service alert currently in action that you can see here.
I’d say just give it a few minutes to an hour and all should be fixed. 
I swear the service alert was not there 15 minutes ago!! I guess i’m gonna wait! Thanks
