I have two pods in my Kubernetes cluster - one is connecting just fine to my MongoDB Atlas cluster, the other is failing due to the following exception:
Caused by: com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches WritableServerSelector.
Client view of cluster state is {type=REPLICA_SET, servers=[{address=MY_MONGO_SERVER1:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.SocketTimeoutException: connect timed out}}, {address=MY_MONGO_SERVER2:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.SocketTimeoutException: connect timed out}}, {address=MY_MONGO_SERVER3:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.SocketTimeoutException: connect timed out}}]
Now I'm not sure why one pod is able to connect, while the second one fails. We have another environment (production) that has similar configuration and all is fine with that environment's pods. Also, that environment runs on same Atlas cluster-sized DB, with similarly configured Kubernetes deployments.

Getting the Below error when trying to connect to mongodb via PySpark(Google DATAPROC), its happening both locally and in Dataproc in GCP. We’re getting the below errors:
py4j.protocol.Py4JJavaError: An error occurred while calling o68.load.

I’ve been using the below command to submit jobs to dataproc. But we’re not sure where the problem is.

This is my connection URI
"mongodb+srv://myUserName:myPassWord#myHost/myDb?retryWrites=true&w=majority"
My user has readAnyDatabase role. But when I try to find a document I get this error.

If you see it's able to connect to the Mongo DB (I am infering this from the fact that it is able to discover all the nodes from myDb-shard-00-00 to myDb-shard-00-02), but gives this error when trying to read some data.
I have connected to other mongo dbs (different uri) with the same code and successfully read documents. So, I am guessing that there should be something wrong with my configuration? Or is it something else? What is the direction that I should be looking at to debug this?
I created a test DB in Mongo Atlas.
Below is the uri that I am using in the application properties of the spring boot project.
spring.data.mongodb.uri=mongodb+srv://user:pwd#cluster.mongodb.net/test?retryWrites=true&w=majority&ssl=true&sslInvalidHostNameAllowed=true
I tried this one as well.
spring.data.mongodb.uri=mongodb+srv://user:pwd#cluster.mongodb.net/test?retryWrites=true&w=majority
I have whitelisted my IP in the Atlas
My password contains only the alphanumeric character, no special character.
Still, I get the below exception.
