When the project is deployed to Alibaba Cloud server ubuntu14.04, a restart will occur. Looking at the log, it says
Db.prototype.authenticate method will no longer be available in the next major release 3.x as MongoDB 3.6 will only allow auth against users in the admin db and will no longer allow multiple credentials on a socket. Please authenticate using MongoClient.connect with auth credentials.
I saw someone had the same problem here https://github.com/Automattic ..., it was said to be caused by mongoose. I still reported this error after upgrading mongoose to the latest version. . .
This is my link to mongodb:

mongodb://blog_runner:safeblog@127.0.0.1:27017/blog-app

blog_runner has read and write permissions. How to solve it?
