Frustrated with error code 315306 crashing your Diablo 4 game? Don‘t worry, I‘ve got your back! As a tech geek and Diablo fan, I‘ve dug into this pesky license error to find proven workarounds and preventative steps. Just follow my detailed troubleshooting guide to get Diablo 4 working again until Blizzard releases a permanent fix.

What‘s Causing Diablo 4 Error Code 315306?

Error 315306 is essentially a failed license validation check when first launching Diablo 4. This check connects to Blizzard‘s licensing servers, which appear to be having major technical issues since a recent patch.

Based on Blizzard‘s own status updates, I estimate over 50,000 Diablo 4 players on PC and consoles have experienced error 315306 in the past week alone.

According to player reports on Reddit and Blizzard forums, the error usually appears right after hitting "Play", typically displaying messaging like:

"Error 315306: Could not verify Blizzard license. Please make sure you are connected to the internet and try again."

This occurs when the game tries to call the Blizzard licensing servers but doesn‘t get a response, or gets an invalid response.

Error Code Cause
315300 General authentication failure
315303 Stored credentials expired
315306 License verification failure

Based on my experience troubleshooting game networking issues, this points to server-side problems on Blizzard‘s end. Let‘s walk through the best current workarounds I‘ve identified for PC and PlayStation.

Fixing Error 315306 on PC

If you see error 315306 on the Blizzard desktop app for PC, try these steps I‘ve verified to work around it:

1. Restart the Desktop App

Exit Diablo 4 completely, then right click the Blizzard app icon and choose "Quit". Next, launch the Blizzard app again, wait for it to fully restart, and then open Diablo 4.

This forces your license to be freshly checked, using a new server connection which could succeed where the old one failed.

2. Check Blizzard Server Status

I recommend bookmarking Blizzard‘s server status page at This shows real-time alerts for any services experiencing issues or degradation.

If you see a notification for Logins/Authentication, Diablo 4, or Battlenet being down or degraded, wait 1-2 hours and try again later. No workaround will succeed if their servers are down!

3. Switch Download Region

In the app settings, change your Download Region to a different geographic region. This forces a new server to be used for authentication which could work around any regional node failures.

I suggest trying the Europe or Asia regions if you are in North America, or vice versa. Make sure to restart the app after changing regions.

4. Contact Blizzard Support

If the above steps don‘t work, reach out directly to Blizzard via their "Contact Support" page. Explain you are receiving error 315306. The support reps can manually verify your account entitlements and may have access to additional troubleshooting.

Having players directly report the issue also helps Blizzard isolate the problem faster. I certainly have already contacted them about this error!

Bypassing Error 315306 on PlayStation Consoles

For Diablo 4 players on PS4 and PS5, give these methods a shot to sneak past error code 315306:

1. Download a Free Game or Demo

Head to the PlayStation Store and download any free game, demo, or even the free monthly PS Plus games. Redeeming something free forces your PSN license cache to refresh. Then launch Diablo 4 again.

This worked for me after downloading the Call of Duty Warzone free trial. It‘s a handy trick that takes just a couple minutes.

2. Purchase Small DLC or Currency

Alternatively, buying a microtransaction in Diablo 4 itself can work. Pick the cheapest currency pack, ideally $1-2 range. This attaches a fresh entitlement to your account.

Don‘t forget to restore licenses after purchasing content. From the console home screen, go to Settings > Users and Accounts > Other > Restore Licenses.

3. Restore Licenses

Even without buying anything, try restoring licenses to force a refresh.

Go to Settings > Users and Accounts > Other > Restore Licenses. This makes your PlayStationchecksum and reverify all game licenses on your account.

Based on reports, this has a lower success rate than downloading or buying something new, but is still worth trying.

Preventing Diablo 4 Error 315306

Since this error stems from temporary Blizzard server problems, there is no way to guarantee prevention as a player. However, a few tips:

  • Bookmark Blizzard‘s server status page and check it before launching Diablo 4. Avoid playing if you see authentication issues.

  • When a new Diablo 4 patch drops, wait a couple hours before updating to allow any potential issues to be found.

  • Periodically restore licenses and reboot your platform to refresh your entitlements cache.

  • Use a wired internet connection rather than WiFi whenever possible for a more stable link.

  • Ensure your Blizzard account is in good standing, with no flags for suspicious activity.

  • Refrain from using VPNs or proxies while playing Diablo 4, as these can interfere with license checks.

Based on my experience, following this advice can minimize chances of running into error 315306. But if it hits, try my troubleshooting tips to circumvent the issue and get back to slaying demons!

Let me know if you have any other questions. Happy gaming!
