When a request comes after my project starts running in Kubernetes;

INFO logs are being printed in console. After a while, the “Connected to Node” logs are interrupted and the message “Got notified from Channel as inactive, attempting reconnect.” logs are starting to increase. Eventually all requests timeout.

I tried the QueryServiceConfig.create(0, 12, 1); suggestion but it didn’t work. Anyone have an idea for a solution?

It’s likely that your client cannot connect to your server. SDK Doctor is useful for troubleshooting client connectivity. SDK Doctor | Couchbase Docs

There may also be additional information in the exception.

Hi, I updated the couchbase java sdk version from 2.7 to 3.6. I’ve been observing for a while. The problem seems to be solved.
