Email-phpmailer use NetEase 126 to send mail questions

Recently using Phpmailer library to connect NetEase's smtp.126.com mail service send mail always return connection failed
Mailer Error: SMTP connect() failed.
The same is true for the Swiftmailer library.
This is the use of the new NetEase account will have problems, because the new NetEase account needs to open the client authorization code to use the SMTP service. The old account is not the problem.

How do I use this authorization code to connect with the SMTP of NetEase? Or are there other ways to troubleshoot connection failures?

In my opinion, the client authorization code is like an alternative to a password.
