Encountering Diablo 4’s 30008 error during login attempts after a queue could be due to issues with the game servers or your internet connection. Problems with your DNS server or NAT type might hinder connectivity. Server overload from high game traffic could also trigger this error. Solutions to resolve this issue are available in this guide.
Listed Down Solutions To Solve Diablo 4 Error Code 30008:
- Downgrade Graphic Drivers.
- Understand Your NAT Type.
- Verify & Repair Game Files.
Downgrading Graphic Drivers
It seemed like after updating my graphics driver for the first time in a while, I started having freezing issues in Diablo 4. These problems popped up right after the update: freezes when I opened my inventory or the world map, random 5 to 10-second freezes, and eventually faced the error code 30008.
To fix it, I tried rolling back to a slightly earlier graphics driver version, and surprisingly, it completely fixed everything. No more freezes, crashes, or any issues whatsoever since then and it seems like this solution also helped numerous other players.
Understand Your NAT Type
If the previous methods didn’t fix the error, a restricted NAT Type might be the issue. NAT types are Restricted (Type 3), Moderate (Type 2), and Open (Type 1). Restricted NAT makes online gaming tough, while moderate works fairly well, and open has no issues.
You should first check to see if your NAT type is restricted or not. The simplest method of checking your NAT Type in Windows 10 is through Xbox Networking:
- Go to your Windows 10 settings from the Start menu and then click on Gaming.
- Once in > click on the Xbox Networking tab > it will run the test for you.
If it shows Restricted instead of Open, proceed to change your NAT type. If it’s already open, skip this step. To achieve an Open NAT type, enable UPnP in your router’s settings.
How To Enable UPnP & Get Open NAT Type
- Open your internet browser > enter your router’s default IP address found on the router.
- Log in using the default username and password
- Navigate to the UPnP setting in the router’s interface, often located under “Advanced” or “Network Settings.”
- Enable UPnP. Your router will reboot, and upon checking, your NAT type should be Open.
Now, try to launch Diablo 4 again and see if you can log into the game without encountering an error code. If you are still running into the error, move on to the next solution.
Verify & Repair Your Game Files
Due to an almost endless amount of reasons, your game files can sometimes get corrupted or disappear entirely. These corrupted or missing game files can also lead to error code 30008. While this is not very common, it is still worth checking off as a potential cause. Fortunately, Blizzard’s Battle.net, the official launcher for Diablo 4, has a great built-in feature that can scan for any potential missing or corrupted game files and repair them.
Summing Up Error Code 30008 Issue
The Diablo 4 error code 30008 seems to affect many players worldwide (Blizzard & Reddit). Fixing it might be straightforward if it’s related to DNS or NAT-type issues, but some might face difficulties due to internet providers’ restrictions. I discovered that rolling back graphics drivers solved the problem for me and others.
While the official Diablo 4 Twitter has directly addressed this error, the issue persists for some. People on Twitter express frustration and share experiences.
