Winlogbeat error on alias

Hi

I got an error on my client with Winlogbeat running below is the error log

2023-11-22T03:58:49.082+0800 ERROR [publisher_pipeline_output] pipeline/output.go:154 Failed to connect to backoff(elasticsearch(https://54.255.5.84:9200)): Connection marked as failed because the onConnect callback failed: resource 'winlogbeat-7.9.3' exists, but it is not an alias

Hoping for some answers as there are no logs going into kibana / elasticsearch

Thanks

Did you do the the "setup" step from Winlogbeat quick start: installation and configuration | Winlogbeat Reference [8.11] | Elastic?

That should be what configures index lifecycle management (ILM) and creates the alias which points to the current write index.
