Diablo Immortal is a newly established action MMORPG set between the events of Diablo 2 and Diablo 3. Although the developers conducted a beta testing phase, the game encountered an “Unable to authenticate” error. Specifically, this means that when players try to sign up for Diablo Immortal with their Battle.net accounts, they receive an error message. Today, I’m going to help you fix the Diablo Immortal “Unable to Authenticate” error.
The error has now been identified, but an official fix is yet to be released. Until then, I’ve studied the issue and prepared a guide to explain the causes and fixes for the Diablo Immortal “Unable to Authenticate” error. So, without further ado, let’s dive into it.
What Fixes Can I Try for Diablo Immortal Unable to Authenticate?
Battle.net is a platform that allows instant messaging, digital distribution of games, social networking, and, most importantly, an all-in-one DRM platform for all Blizzard Entertainment-published games. However, Diablo Immortal is currently encountering an authentication error. To help you out, I’ve analyzed everything and found some possible causes, like temporary server downtime and corrupted cache files. Below, I’ll explain all of the fixes in detail to help you solve the error.
Check the server status.
It’s possible that when you’re trying to log into your Battle.net account, the game’s server might be down. In such a case, you won’t be able to log in and will see the “Unable to authenticate” error. Before trying any other fixes, make sure to check the server status through Blizzard Entertainment’s official social media handles. If the server is down, they will surely mention it.
Unfollow the System Requirements
Every game has specific minimum system requirements to run appropriately. Diablo Immortal is no exception. According to the official terms, your device must have a video processing unit such as Adreno 512 or Mali-G62 MP3 or higher. You can check this through an application like CPU-Z, available on the Google Play Store.
Corrupted cache files
While installing the game, it may create a few corrupted files in the application’s memory. This can act as a hurdle to running the game properly, leading to the “Unable to authenticate” error. I recommend you clear the Diablo Immortal app cache files from your device settings: go to application management, find Diablo Immortal, and clear the cache.
With the given fixes, I assume your Diablo Immortal “Unable to Authenticate” error has now been fixed. However, if you continue to experience the issue, contact Blizzard Entertainment’s official support to get a permanent solution.
