Error when logging in for online TV streaming

Welcome to att magic.  

You are an att U-verse TV subscriber, right?   

Please post back if this doesn’t resolve in a day or two.  

Hi @MPE1230, Let's see if we can get you back to watching your favorite shows.

We recommend that you clear the cache and cookies and uninstall and reinstall the apps.

• Also, we suggest that you reset your U-verse password and wait a full 24 hours because this will re sync your account.

Also a few troubleshooting steps for your streaming concerns:

1. Make sure you are using the correct member ID to sign in. 
2. Restart the device.
3. Delete cache. Varies on phone, browser or device operating system.
4. Uninstall and reinstall the app
5. Verify you have the latest software/ operating system on your phone or tablet 
6. Turn off other apps that may be in use
7. Make sure you have U-verse TV service and an appropriate package – if you do not have U-verse TV, you can see if it is available by signing into your account at att.com.
8. Reset your password – This can help sync up your account.
9. In some instances, restoring the phone has resolved app function. You may lose pictures and other data if this is performed. 

Let us know if this helps.

I've cleared the cache and tried other suggestions yet still have the same issue on multiple browsers.

Hello.  What device are you attempting this from?

@gr8sho 

A MacBook Pro. I've attempted on multiple browsers (Safari, Chrome, Firefox, and Opera).

@MPE1230 
I thought so since you mentioned Safari.   I can test for you on a Windows machine as I haven’t tried this lately, but even under the best of circumstances, that authentication mechanism has been flakey.  Usually it takes several repeated attempts to get one to go through and stick.
