‘filebeat-7.11.1’ exists, but it is not an alias'

Hi,

I'm encountering an issue with Filebeat 7.11.1 after a recent restart of our Elasticsearch cluster. Prior to the restart, everything was functioning smoothly, but since then, Filebeat has stopped sending data to Elasticsearch.

The following error is consistently appearing in the logs:
"Template filebeat-7.11.1 already exists and will not be overwritten. [index-management] idxmgmt/std.go:298 Loaded index template. [publisher pipeline_output] pipeline/output.go:154 Failed to connect to backoff (elasticsearch (https://X.X.X.X:9200)): Connection marked as failed because the onConnect callback failed: resource 'filebeat-7.11.1' exists, but it is not an alias"

Data stream : "filebeat7.11.1"
Index pattern : "filebeat-*"

Any assistance you can offer would be most appreciated.

Thanks in advance.
