Filebeat doesn't send logs to Logstash

Elastic Stack Beats
1

Hey my filebeat stopped sending logs last friday and I'm wondering as to what reason is it:
journalctl -fu filebeat -> ERROR Failed to connect to backoff(async(tcp://<logstash_ip>:5044)): dial tcp <logstash_ip>:5044: connect: connection refused
And my filebeat config is:

filebeat.inputs:
- type: log
  paths:
   - '/var/lib/docker/containers/*/*.log'
  json.message_key: log
  json.keys_under_root: true
logging.level: error
output.logstash:
  hosts: ["<logstash_ip>"]

telnet <logstash_ip> 5044 or 8086 or 9200 all works and there is connection

Logstash as input has:

   input {
      beats {
        port => 5044
        client_inactivity_timeout => 68000
      }
    }
