I'm getting this error while installing and enrolling fleet server on a windows host " Error: fleet-server failed: context canceled "
(STARTING-\>FAILED): 1 error: file is not a certificate adding C:/elasticstack-ca/elasticsearch-ca.crt to the list of known CAs accessing 'output.elasticsearch'
Need a solution on urgent basis
Mine is a self managed elastic stack.

The provided error message indicates that `C:/elasticstack-ca/elasticsearch-ca.crt` is not a correctly formatted cert. Can you verify this?
