What does the error message mean?

Don’t worry, despite the intimidating message, nothing is wrong with your Diablo 4 account. Some player have feared that “online play is blocked” meant their account was suspended or disabled for some reason. However, the error message actually just means somewhere along the way when authenticating your account to login to the Battle.net servers—and therefore Diablo 4—something prevented it from authenticating.

More often than not this just means there is some sort of network issue, usually on Blizzard’s end. A good first step is always to check the @BlizzardCS Twitter account to see if they mention any server downtime or maintenance. From there, check to make sure the servers didn’t just come back up which can lead to them being overloaded for a few minutes. If either of these are true, simply wait a little bit and try connecting again and you should have no error.

Ways to fix “online play is blocked” from your end

Even though it’s usually an issue on Blizzard’s end, sometimes it can be a hiccup on your end. Try these easy steps to rule out the possibility that something on your end is causing the error message:

  • Make sure you have a stable internet connection. If you are connected wirelessly, consider connecting to your internet directly via a wired connection as it’s much more stable.
  • Double-check that you’re on the latest version of the game. On all platforms, you can do this by completely closing out the game and relaunching it, which prompts Diablo 4 to search for an update.

If you have tried both of the above steps and are still getting the error message, try again in a few minutes to see if it was just server congestion. These are the best ways that we know how to fix “online play is blocked” in Diablo 4 and will hopefully resolve your issue.
