Diablo 4 Error Code 315306 – Unable to Find a Valid License for Diablo 4

“Unable to find a valid license for Diablo IV.”

This error code first appeared when players tried to access Diablo 4 before the servers officially launched. It has since been acknowledged by the official Diablo account on Twitter.
