If you are getting Error_3022 when trying to use the Auction House, this is to let you know that Blizzard is working on the issue.
For now, here is the current work around to get your account working again.
1. Go to the Battle.net website and log in.
2. Go to your billing address.
3. Click Edit when at your billing address.
4. Do not edit anything and press Save.
5. Attempt to use the Auction House again.
For some reason, people with valid billing addresses are being locked out of using the Auction House, even though the Beta is not using your billing address for anything as Beta Bucks aren't real money. This work around should help you guys out.
