Server Queue On Aug. 6 Leads To "Connection Failed" or "Undefined" Error

When I got BF6 Early Open Beta and then I hit to launch the game until this error message and the error code are ERROR CODE 1:8600 1S:66003S:4688822970:0B, I saw many people are struggle about the error. And yet this is not my internet fault. Is the game fault or a server fault.

Any suggestion fix pls ea.
