Logstash can not start up after I update the license from trial to basic?

[KeithTt]

I followed this page to update the license:
https://www.elastic.co/guide/en/x-pack/current/installing-license.html

I delete the username and password in the pipeline config file of logstash, and don't modify anything else.

Here is my pipeline config file:

input {
  beats {
    port => 5044
    codec => "json"
  }
}

output {
    if [type] == "zixun-nginx-access" {
    elasticsearch {
        hosts => ["192.168.3.56:9200","192.168.3.49:9200","192.168.3.57:9200"]
        index => "zixun-nginx-access-%{+YYYY.MM.dd}"
        document_type => "%{[@metadata][type]}"
        template_overwrite => true
    }}
    ...
}

What is the problem?
