Logstash connection error

Hello guys
Every time I try to check the logstash data I get an alert that the data cannot be received in Kibana
"Module status
Check that data is received from the Filebeat logstash module
No data has been received from this module yet"

The logstahs service is active, but I can't receive the data, and for some reason, Linux also doesn't recognize the service. I'm using ubuntu 18.04

I don't know what else to do to solve the problem. Help me please
