Why won’t HBO Max accept my email

HBO Max may not be accepting your email because their server is down for planned maintenance, or the email address that you are using may not be unique and is already in use by another HBO user.

Other reasons as to why HBO is not logging you in could be due to these reasons;

Reason 1. Incorrect login credentials

You could be trying to log in to your account with the wrong email address. Make sure you are using the correct credentials, otherwise HBO will not recognize your registered account.

Are you accidentally using caps lock, or including unnecessary spaces?

If you have originally setup up your HBO Max credentials to be auto-filled, and you have since then updated your email address or password, your device will still try and log you in with the older details.

Reason 2. Cache files are too full

Cache files are temporary data that is saved onto your device to improve the loading time of HBO when you launch the application.

Over time, these files will become too full, and the data can become corrupted which will interfere with you being able to access your account successfully.

Reason 3. Outdated App software

Your Home Box Office application could be due to an upgrade.

If your video streaming service is operating with older software, this can potentially interfere with the successful running of the app. The service is continuously being updated to get rid of bugs and improve its performance.

Reason 4. Exceeded profile accounts

HBO Max allows account holders to have five profiles under one account, and stream on a maximum of 3 devices at the same time.

If you are trying to stream on a 4th platform, you will receive an error message, prohibiting you from gaining access to your library full of Warner Bros media to choose from.

Note, accessing your HBO Max account on a different device needs to be replicated with the exact same login details that you used on your original device.
