Zhenglan Energy Saving failed to obtain verification code

Network failure.

Check the network, or check whether the security software has set up a network block. The reasons for failure to obtain the verification code are:

1. The user’s mobile phone number is blocked by the operator. I once complained to the operator that such notification text messages were spam, causing the text messages to be blocked by the operator.

2. Blacklist settings such as mobile phone SMS security software. Once upon a time, relatively strict interception rules were set up in mobile phone text messages.
