I have 2 cluster with same specs but from last two days me one cluster works fine with same queries but second cluster give me a issue frequently one is “MongoNetworkTimeoutError: connection 2 to IP timed out” and 2nd is “could not connect to server with in time limit”
even both clusters have same indexes CPU and Memory Usage also same for both
What size cluster? What region are both of the cluster deployed within? Have you added IP firewall rules to permit access from your IP?
