      Today, I changed my connection from Node.js (12.18.2) to MongoDB (4.2.9) to using SSL like so:

      MongoClient.connect("mongodb://my_user:my_password@1.3.4.5:27017/documentDB?maxPoolSize=500&ssl=true", { useNewUrlParser: true,
    useUnifiedTopology: false, 
    server: {
      sslValidate:false,
      checkServerIdentity:false
  }
} ...

      The functionality seems there and everything works, however I get this warning:

      DeprecationWarning: Setting the TLS ServerName to an IP address is not permitted by RFC 6066. This will be ignored in a future version.

      I was surprised not being able to find anything about it neither here nor via Google. Maybe I did search wrong?

       

      Note: The reason for me to use useUnifiedTopology: false is that I need the silently (sic!) removed events for close and timeout.

      See https://jira.mongodb.org/browse/NODE-1340

      "These events were intentionally omitted from the unified topology, I wasn't clear that this was useful metadata for users. We were using it internally for reconnect logic, but that has been completely rewritten with the unified topology anyway.. From a user's perspective, you shouldn't ever care about connects and reconnects, just that your operation runs on a server. Is the reconnect event useful to you?"

      Yes, for me, there are necessary.
