@chewy, just double checking that you are using the new xbox one SmartGlass app when trying to connect to your xbox one (verses the 360 SmartGlass app you used with your 360).

Microsoft ditched SmartGlass in favour of the new Windows 10 Xbox app. That being said, having your Windows account tied to SmartGlass and Windows 8/.1 cause the app not to function. I'm suspecting it has something to do with the App running in the BG, and
not letting any other instances connect to SmartGlass.

Hi Rick,

Thanks for reaching out to us in the forums with this question. Sadly, the answer to your question may be that the Xbox 360 SmartGlass app has been officially retired and the app and its content are no longer being offered. However, what we recommend you
use instead is our Xbox App for your Windows 10 device. You can sign into your Microsoft account there.

Xbox 360 SmartGlass app retirement

I hope that this helps out!

having the same issue. I have searched the forums and used google to try to search for a solution to no avail. my 360 is already set to allow smartglass app connection. I have reinstalled xbox 360 smartglass on my windows 8.1 machine (lenovo lynx K3 tablet).
the xbox 360 smartglass app on my android device (galaxy s3) can connect just fine. (had a similar issue with the xbox one smartglass app on my tablet, but found that to be a software firewall (comodo) issue. with the 360 smartglass app, I have tried disabling
the firewall and I still get a message the app cannot find the console). when I check the properties of the app in the task manager, it points to a folder of where it was installed, and not an executable. not sure if this is what is causing the issue. both
the 360 and the tablet (I have even been prompted by the app to re-sign in and I used the same account information)are signed in under the same account and are on the same wireless network. and again, I can sign into the xbox one smartglass app just fine after
I resolved the firewall issue (to allow the application associated with the app to be allowed connection). I have also reset my router (as I found other suggestions in other posts advise to do. I feel as I have exhausted every conceivable possibility, and
yet, still does not work. HELP!!!!
