Im having a problem connecting from splunk db connect to MongoDB replica.
I can telnet the ip of mongo replica to splunk, also tried to connect the mongo primary db and yielded successfully. But when connecting to mongo replica db, Im encountering an error "Database connection MongoDB is invalid. not talking to master and retries used up"
splunk db connect version is 3.1.4
splunk version is 7.2.3
Can you help me if there is a problem on my configuration below.
