If you have been suffering from the Diablo Immortal Unable To Connect error, you aren't alone. And frankly, it wouldn't be a new massive online game if it didn't have connection issues. This is almost becoming a rite of passage that players need to go through before they can play their chosen game.

But knowing that this is typical when new games launch doesn't make it any more acceptable. And for players who have been trying to access the game, a far more important question is how they can actually fix the issue.

And that's the question we intend to answer here.

How To Fix The Diablo Immortal Unable To Connect Error

Before we get into any potential troubleshooting solutions, there are a couple of checks it's worth making. First of all, check the @BlizzardCS Twitter feed, which will let you know if there are any known service issues. If there are any outages, wait until those are resolved before trying again.

The second thing you should do is ensure that your device meets the minimum system requirements to support the game. These are as follows:


  • CPU: Intel Core i3 or AMD FX-8100
  • RAM: 4 GB
  • OS: Windows 7 / Windows 8 / Windows 10 / Windows 11 (64-bit)
  • Video Card: NVIDIA GeForce GTX 460, ATI Radeon HD 6850, or Intel HD Graphics 530


  • OS: Android 5.0 or higher
  • Processor: Snapdragon 660 / Exynos 9611 or higher
  • Video: Adreno 512 / Mali-G62 MP3 or higher
  • Memory: 2GB RAM


  • Hardware: iPhone 6s and newer
  • Operating System: iOS 11 and later

It's important to note that these are the minimum recommended specs for the game. So if you are using a device that doesn't meet these requirements, then you are likely to encounter all sorts of performance issues. No amount of troubleshooting is going to resolve them.

But assuming you do have a system that's capable of running Diablo Immortal, what then? Here are your best bets for resolving the problem.

Troubleshooting Steps

  • Start by checking for any outstanding game or system updates. If there are any, install them, then test the game again.
  • Next, try restarting your device and relaunching the game.
  • If you are on WiFi, you can try switching to a mobile data connection. And if you are using a PC, if possible try switching from WiFi to a wired connection, as this can improve stability.
  • If you are using an Android device, try clearing the app cache. You can access this by going into settings > app storage. Select the Diablo Immortal app, then press Clear Data.
  • You can also check your home internet connection is actually working properly. Try a different game or app, run a speed test, and try to minimise the amount of traffic on your network. You can even restart your router to refresh your connection.
  • If you use a VPN, try switching it off. This will connect you to a different game server. And conversely, if you are struggling to connect to your local server, then using a VPN may enable you to connect to one in a different location. This can be effective if your local server has an outage, or too much traffic.

If you've reached this point and you are still experiencing the unable to connect error, you really have two options left to you. The first is to uninstall and then reinstall the game. And the other option, which you can do before or after you've tried uninstalling the game, is to contact Blizzard support for additional help.

What Causes The Unable To Connect Error?

So what is the connection error, and what is its underlying cause? Fundamentally, it is an error that occurs when players are unable to connect to a server and are therefore unable to play the game.

The error is potentially caused by a variety of different issues. Hence the range of potential fixes that we outlined earlier. It makes it very difficult to state definitively what the cause will be in each specific case.

But one thing we do know is that this is not an uncommon issue with new games, especially those that are played online. There are a few common reasons for this.

One is that typically there is a surge in traffic with new games, and sometimes the servers are simply unable to cope. This problem tends to resolve itself over time, as traffic stabilises and server capacity grows.

There are also sometimes issues that get resolved by early patches and updates.

Whatever the underlying cause, try the fixes we've suggested, as these will be your most likely shot at a resolution.
