Getting endpoint connection exception while connecting to couchbase

Java SDK

I am facing following exception when migrated my app developed to the aws instance. In my local setup there was no replica’s created. However on my aws setup i have replicaNumber set to 2. Please suggest what am I doing wrong.

Can you please try 2.1.2-dp? I think it’s a regression introduced in 2.1.1 that has been fixed in 2.1.2:

<dependencies>
    <dependency>
        <groupId>com.couchbase.client</groupId>
        <artifactId>java-client</artifactId>
        <version>2.1.2-dp</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>couchbase</id>
        <name>couchbase repo</name>
        <url>http://files.couchbase.com/maven2</url>
        <snapshots><enabled>false</enabled></snapshots>
    </repository>
</repositories>

There will be a 2.1.2 coming soon, so if this fixes the issue please upgrade. Alternatively try 2.1.0 for now and then go to 2.1.2 once released.
