The beta is missing from Battle.net
First distinguish an opt-in from an actual invitation. Check that you are using the account associated with your access. Then follow the installation steps. This avoids troubleshooting a different WoW client by mistake.
Use Blizzard’s access notice to verify the official procedure. We cannot inspect or change your account entitlement.
The client opens but disconnects
Record your region, exact error and time. Compare these with a relevant official notice before applying a fix. A region-specific networking report is not evidence of a global outage or a universal repair.
The EU routing note describes a reported network issue; it is not a live status indicator.
Graphics or launch errors
Confirm the GPU model and consult the hardware evidence page. Do not delete installation folders or change security settings based on an unverified workaround.
Still unresolved?
Use Blizzard Support with your region, operating system, GPU, client version and exact error. Never post passwords or access tokens in a public report. We do not provide a speculative registry edit or unofficial beta-key download.
