Perhaps there's SNI tests somewhere we could try to run? It's really troublesome to support openssl features when there's no tests for most of them :-(

Any update here? I am trying to connect my JRuby 9.1.17.0 app to MongoDB Atlas with ssl: true. It's not able to connect to servers. Same thing works with Ruby 2.2.3 app.

@headius I am able to reproduce the issue with Ruby Mongo driver connecting to a TLS enabled MongoDB cluster.

jruby-9.1.15.0 :002 > client = Mongo::Client.new("mongodb+srv://<Username>:<Password>@sqcluster0-rntvf.mongodb.net/test")
 => #<Mongo::Client:0x2148 cluster=sqcluster0-shard-00-00-rntvf.mongodb.net:27017, sqcluster0-shard-00-01-rntvf.mongodb.net:27017, sqcluster0-shard-00-02-rntvf.mongodb.net:27017>
jruby-9.1.15.0 :003 > client.list_databases
=> Mongo::Error::NoServerAvailable: No server is available matching preference: #<Mongo::ServerSelector::Primary:0x2162 tag_sets=[] max_staleness=nil> using server_selection_timeout=30 and local_threshold=0.015
	from (irb):3:in `<eval>'

Do you need anything else? I can share a dummy username and password to connect with the real mongo cluster on MongoDB Atlas.

@estolfo Would it be safe to set hostname on the socket in a forked repo and use it to connect to MongoDB Atlas for now?

@prcongithub My apologies, I don't work on this project anymore. I suggest reaching out to @p-mongo or @saghm instead.

SNI works with jruby 9.1.17.0 and 9.2.0.0 when using java 8.

We enabled it in mongodb/mongo-ruby-driver@e7421ba.

thanks Oleg, was pretty sure its already working, since Java 8 is the preferred stack this will stay as is.
also believe they also added the Java API in 8, so this will stay a wont fix for Java 7 users ...

Should this ticket be closed? It looks like SNI is supported with java 8 and higher and not supported with java 7 and this is the desired behavior going forward.
