How to Fix Diablo 4 Beta Not Launching Issue

If you can’t launch the Diablo 4 beta during the first open beta weekend, there can be numerous reasons for this. First thing first, make sure to read our guide on how to start the Diablo IV beta. If you don’t meet all of the requirements there, that’s probably why the game can’t be launched. Second, given that Diablo 4 is an always-online game make sure that your internet is working properly and without any issues. Try other online games and see if they are working without any problems. If possible, always use an Ethernet cable instead of a WiFi network. WiFi networks are often unstable, which can cause connections issues and other problems.

Furthermore, make sure that Diablo 4 is listed as “secure” in your antivirus and firewall apps. If your security apps don’t have Diablo IV under “trusted” apps, they can prevent the game from starting and connecting to the servers. Power-cycling your modem/router is also one of the possible solutions when the game refuses to launch. To do this, follow these steps:

  • Turn off your router.
  • Unplug it from an electrical outlet.
  • Leave it unplugged for around 2 to 5 minutes.
  • Plug it back in and turn it on.

Oftentimes, the game will not launch when some files are missing or corrupted. To prevent this, use Battle.net’s Scan and Repair feature to make sure that everything is alright with your installation:

  • Open the Diablo 4 homepage in the Battle.net client.
  • Click on a blue cog icon next to the “Play” button.
  • From the menu, select “Scan and repair”.

If none of the above solutions helps, try completely uninstalling and reinstalling the game. In many cases, a fresh installation of the game fixes most of the problems. For more troubleshooting, check out our Diablo 4 Crashing and Freezing guide.
