No data from logfile on a new index

Elastic Stack Kibana
2

I solved the problem:
First I had an error, that my ES died. the reason was wrong file permission, so I made chmod -R 1000:1000 on local-ELK/elasticsearch/data.
After that I noticed, that in my output part are multiple errors:

output {
  #stdout { codec => rubydebug } 
  elasticsearch {
    hosts => ["http://elasticsearch:9200"]  
    user => "kibana"
    password => "3last1c"
    index => "weechat_index"
  }
