Hi guys,

I just upgraded elk stack from 7.15.0 to 7.16.0.

Everything is working fine except Logstash.

It ends up failing to start. I checked the system logs and found the following error.

Error:

```auto

logstash[20212]: Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties

systemd[1]: logstash.service: Scheduled restart job, restart counter is at 14.
systemd[1]: Stopped logstash.

```

The _0x7488db31_ keeps changing at every restart try.

I tired to downgrade Logstash to 7.15.0 and it works fine. The error only shows up at 7.16.0

Please help me figure out as to what is happening.

Regards,  
Neerajkumar G.

Perhaps you have http.enabled in your logstash.yml and you need to change that to api.enabled. See [this](https://github.com/elastic/logstash/pull/13481) PR.
