Something’s Gone Wrong (SmartHomeManager) not working

A while back I went through 2 months of not being able to use the app for similar problem.  If you’re using the same credentials to login as the myAtt app, likely nothing you can do about it for now.  

FWIW, I successfully logged in myself.  

Hey, @rosario_gzm.

We're here to help you use your Smart home manager. Let's work on a fix.

We do have a web version of the Smart Home Manager you can use, but if you really want to use the app version, we'd recommend clearing your device's cache in general storage and also restarting your device.

In the meantime reinstall the app to fix any bugs It might have-

Before you restart the app, try clearing the app cache first.

To clear the app’s cache on Android:

• Open Settings.
• Tap Apps.
• Find Smart Home Manager and select it.
• Tap Storage, then tap Clear Cache.

For iOS:

• Open Settings.
• Go to General > iPhone Storage.
• Locate Smart Home Manager and Tap Offload App.
• Confirm the prompt.

If clearing the cache didn’t help, then the app might have corrupted files.

To fix this, delete the app from your Android or Apple device and reinstall it from the app store.

NOTE :                 

• Make sure you aren’t using a VPN since it can cause issues with connecting to the app.
•  Update the app and the system software to the latest version.
•  Remove any third-party devices that might interfere with the network.

You’ll have to reset the router :

When your network doesn’t respond to anything that Smart Home Manager does, it might be because of a bug or issue on your router.

To do this:

• Turn the AT&T router off and unplug the power cable.
• Wait for 30 secs before restarting the router.
   

Once the router restarts, you should be able to reconnect to the network.

Open Smart Home Manager on your phone or browser and see if the changes you make there reflect on your Wi-Fi network.

Let us know if this helps! If not, we have a few more things to try.

I tried all of he suggested solutions - sill getting the error in the app.

Try turning off your wi-fi on your cell phone and log in using cellular data only.
