Warning after N1QL is executed

Java SDK

Any sort of help is appreciated

Code snippet in Maven project

Cluster cluster = Cluster.connect(connectionString, username, password);
Bucket bucket = cluster.bucket(bucketName);
QueryResult result = cluster.query(“select * from mybucket where accountNo=7027 and type=‘customer’”);

com.couchbase.client java-client 3.1.5 
    <dependency>
        <groupId>com.couchbase.client</groupId>
        <artifactId>core-io</artifactId>
        <version>2.1.5</version>
    </dependency>

Getting the below warning/error. Although I see that apart from this warning I do see the result of my N1QL query in the logs. But when I run multiple N1QL queries in loop in fails.

WARNING: [com.couchbase.endpoint][EndpointConnectionFailedEvent][10s] Connect attempt 1 failed because of TimeoutException: Did not observe any item or terminal signal within 10000ms in ‘source(MonoDefer)’ (and no fallback has been configured) {“bucket”:“optima”,“circuitBreaker”:“DISABLED”,“coreId”:“0xb61bc28500000001”,“remote”:“bp-qa-v5:28091”,“type”:“KV”}
