My application is spring boot based trying to connect to Couchbase using spring-data-couchbase, which opens a bucket on remote Couchbase 7.1.1 EE server and inserts a document.

Spring Boot Version: 2.3.1.RELEASE Couchbase Server Version: 7.1.1 EE spring-data-couchbase : 4.3.5 (This internally uses couchbase java-client: 3.2.7)

The connection works fine if my application is placed on same server as Couchbase server. If my application is located remotely then it doesn't work

In Couchbase web console I see IP address of server as 0.0.0.0.

I also have couchbase installed on localhost and when my application tried to save data in remote couchbase it instead saved in the localhost. I suspect 0.0.0.0 as the server IP address is causing this.

When the cluster is created at the first time, default IP is populated as 0.0.0.0 (manually changing it has no effect) but in all other installations I have seen default IP as 127.0.0.1

Related Query but couldnt find what was the resolution Couchbase client trying to connect to localhost while configured to remote server

    "I suspect 0.0.0.0 as the server IP address is causing this." Configuring the node to advertise its actual IP address (or better yet, hostname) is indeed one way to resolve the issue. I'm not sure if this can be done without recreating the node. – dnault Mar 23 '23 at 22:19
  • This was due to incorrect Couchbase installation, the guy manually provided 0.0.0.0 address while installing Couchbase instead of default 127.0.0.1 reinstalling Couchbase with correct IP helped – Neha Sahni Mar 30 '23 at 09:46
