Hi,

We are using AWS opensearch. Configuring Fluentd in AWS kubernetes cluster by deploying as daemonset using fluentd-daemonset-opensearch.yaml

Getting below error in pod logs. Please help on it to fix. I couldn't find any help in google regarding fix for this which is connecting to opensearch

==== [warn]: #0 [out_os] Could not communicate to OpenSearch, resetting connection and trying again. No such file or directory @ rb_sysopen - (Errno::ENOENT)
