How to solve Error Code 315306 'Unable to Find Valid License'

Unfortunately, unlike other errors like Error Code 316703 or Alt-Tab problem, there is no real fix for the 315306 - "Unable to Find Valid License." The reason is because the error is related to the unavailability of the Diablo 4 server itself, and it has nothing to do with the user client or their network type. So, just be patient with the servers and wait for them to make a return.

Once the Diablo 4 server issues have been resolved, restarting the game after a short while fixes any remaining issues for many players. If connectivity issues persist, and if you have VPNs or other third-party apps running in the background, try to run the game after closing these applications. If the issue persists for you, visit the Blizzard Support Desk and file a ticket immediately to resolve your problem.
