I follow the instructions here [Secure your connection to Elasticsearch | Logstash Reference [8.10] | Elastic](https://www.elastic.co/guide/en/logstash/current/ls-security.html) but if I did not put the username/password, logstash reported 401, if I put in the user name /password, the start up of logstash stalled at "Starting server on port: 5044"
Start command:
C:\ELK\logstash-8.10.4\>.\bin\logstash -f first-ssl-pipeline.conf --config.reload.automatic
The content of first-ssl-pipeline.conf:
input {
beats {
port =\> "5044"
}
}
filter {
grok {
match =\> { "message" =\> "%{COMBINEDAPACHELOG}"}
}
}
output {
elasticsearch {
hosts =\> ["[https://localhost:9200](https://localhost:9200)"]
cacert =\> 'C:\ELK\logstash-8.10.4\config\certs\http\_ca.crt'
user =\> logstash\_internal
password =\> root123
}
}

Why do you think it's stalled? Are you expecting additional messages?
It's been a while since I've run logstash, but I don't recall it being very verbose on startup.
