no SNI name sent, make sure using a MongoDB 3.4+ driver/shell.

I have two free-tier clusters on MongoDB Atlas.
Both are basically setup the same on Atlas side.
And both are configured the same in Mongo Explorer, even in the same project.
One works flawlessly, but the other cannot connect, showing this error on "Test connection" while connecting with the actual project and with mongo shell and with mongorestore works without any problems:

com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting to connect. Client view of cluster state is

Hi,
The plugin uses the mongo-java-driver-3.8.0. I will update it to the 4.x to check whether it fixes the problem or not.
