we need to use logstash in https, and this's our configucation:  
input  
{  
http{  
host =\> "0.0.0.0"  
port =\> 8080  
additional\_codecs =\> {"application/json"=\>"json"}  
codec =\> "plain"  
threads =\> 4  
ssl =\> true  
ssl\_certificate =\> "/home/yerikyu/logstash/1673589\_radar.cmic.site\_other/1673589\_radar.cmic.site.pem"  
ssl\_key =\> "/home/yerikyu/logstash/1673589\_radar.cmic.site\_other/radar.cmic.site.pem"  
# ssl\_verify\_mode =\> "force\_peer"  
}  
}  
output  
{  
kafka {  
bootstrap\_servers =\> "0.0.0.0:9092"  
topic\_id =\> "logstash"  
compression\_type =\> "gzip"  
}  
}  
and that it's the log

The error message is pretty clear: `/home/yerikyu/logstash/1673589_radar.cmic.site_other/radar.cmic.site.pem` is not a valid Private Key file. This doesn't appear to be a Logstash specific issue, you need to have a valid Private key and the relevant Certificate file in order to enable https.

If you generated the key and certificate yourself, how did you do it?  
If you received the key and certificate from somewhere, please verify that the files are correct.

For instance you can verify your private key file with

```auto
openssl rsa -in home/yerikyu/logstash/1673589_radar.cmic.site_other/radar.cmic.site.pem -check -noout

```

which should output:

```auto
RSA key ok

```
