I had mongodb instance running on AWS EC2 instance, and I was able to interact with it from java code. Then I had to stop the instance and restart it. I modified the connection details in code. But now when I try to run my application, I get:
com.mongodb.MongoSocketOpenException: Exception opening socket at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:70) ~[mongodb-driver-core-4.0.5.jar:na] at com.mongodb.internal.connection.InternalStreamConnection.open(InternalStreamConnection.java:127) ~[mongodb-driver-core-4.0.5.jar:na] at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:117) ~[mongodb-driver-core-4.0.5.jar:na] at java.base/java.lang.Thread.run(Thread.java:832) ~[na:na]
Though I can connect to same mongodb instance via mongo compass.
