What is Error Code 315306?

• Wait for 5 to 10 minutes and try again: Sometimes, the error can be caused by temporary server issues that can be resolved after a few minutes.
• Restart your PC: A simple restart can help address various connection issues.
•  Use a wired (ethernet) internet connection: Wireless connections can be unreliable sometimes, so switching to a wired connection can help resolve the problem.
• Reset your home network device (router or modem): Resetting your home network device can help resolve any connection issues you may be facing.

• Verify Game Files: The first thing you should do is verify the integrity of the game files. To do this, simply open the "Battle.net" client and then select the game. From there, click on the "Options" button and choose "Scan and Repair" from the list. This should fix any corrupt files and potentially resolve the error 315306.
•  Update the Network Driver: If the above step didn't work, the next thing you should do is update the network driver. To do this, open up the "Device Manager" and then right-click on the network adapter. From there, select "Update Driver" and then follow the on-screen instructions. Once the update is complete, restart your computer and then try launching the game again.
•  Close Background Apps: The last step is to close any background apps you may have running. This could be anything from streaming services to Discord. You can also open the "Task Manager" to see which apps are running in the background. From there, select the apps you want to close and then click the "End Task" button.
