123 15 verification code acquisition failed.

1. First, you need to determine whether the short message is blocked (you can try the verification codes of other platforms, such as QQ, Netease Tik Tok, and login verification codes). If other platforms still don't receive the verification code, the message may be intercepted. 2. If the above situation does not occur, it is necessary to consider whether there is a problem with this platform. If only this platform can't receive the verification code, there may be something wrong with the server. 3. Maybe your number is blacklisted by the operator, which is called operator ban, and it is decided by the operator you use. Once blacklisted, you will not be able to receive the verification code, and generally need to explain it in the business hall. 4. Do not rule out other problems, such as the server carrying too many users or the network.
