I m unable to restart the logstash after updating the conf.d file

Im unable to start logstash after updating the conf.d file in logstash. i checked the logs it is showing as Attempted to resurrect connection to dead ES instance, but got an error. I need to start the logstash now.

You need to provide more context, please share the log you are receiving using the preformatted button in the editor, the </> button.

Also, what you change? How are you running logstash? As a service with systemctl?
