Did you Try to use definite file path for logstash.conf? If so, can you share content of the file?

please find the configuration of my logtash.conf file . Elastic search, Kibana and logstash are running on the same system.

input {
stdin {}
}

output {
elasticsearch {
hosts => ["localhost:9200"]
index => "indextest"
}
}

Something that sticks out to me is that you dont have any filter. Can you try adding filter {} and run it again?
