Unable to start logstash service on Ubuntu server

Elastic Stack Logstash
1

I'm using Elasticseach and logstash 7.10.1 on ubuntu 18.04
Logstash service was working properly, few days ago.
Suddenly it didn't work. I tried to restart logstash service.
But unable to start the service.

What can I do to start logstash service in this situation?

Thank You!

Hello .

I think you could start with checking systemctl status logstash and see any errors .
