HBO Max Sign In

I receive a Service Code: H-191cc3c6-76da-494c-ea4d-b43ea2677a51, upon linking my account to sign in with AT&T, I've done it across all browsers, deleted cache, used private browser, used different devices, & I've double checked if my service for my plan qualified, as it does with the Elite plan for both numbers. I even have an email informing me that I qualify. What gives?

Let's help you to get signed in with HBO Max, @managerkevin!


Another troubleshooting step that you can try is:

  • Make sure you are using the right ID.
  • Change your myAT&T password to a different password. Sometimes there is a conflict with your existing password or a special character causing issues. We suggest changing to a password that you have not used in the past. Once registered, you can try changing it back to your previous password.

Find additional helpful sign in tips when you visit Can't Sign in to HBOMAX - Help & Streaming Solutions. Also, that Service Code appears to be an HBO Max trend. Try the following to resolve your experience.

  1. Unplug the power from your network devices (modem, router, etc.).
  2. Wait 30 seconds.
  3. Reconnect the power to your modem and wait for it to connect to the Internet (about 1 minute).
  4. Reconnect the power to your router and wait for it to connect to the Internet.
  5. Go to and see if the problem is resolved.

If this info doesn't help, you can email HBO Max about the Service Error code along with a description of the problem using our Customer Support form.


Reach back out to us and let us know how it goes. In the event that this is a trend with AT&T, it's something our team needs to know about. We want you to be able to use HBO Max with your eligible plan.
