Hello,

I just installed newest Elastic SIEM on my system. All seems fine at this moment. I have filebeat set up on the server etc.

But when I try endpoint security then I run into a problem and I get an error that I can not find how to solve:

```auto
siem@siem:~/elastic-agent-8.1.0-linux-x86_64$ sudo ./elastic-agent install \
> --fleet-server-es=http://172.23.27.98:9200 \
> --fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE2NDY4MjU0NTQ2NzU6V09RbURVak9RMy0tUG0yeVZ2b3ZtUQ \
> --fleet-server-policy=34da2970-9f9c-11ec-83d5-65e20cafef36 \
> --fleet-server-insecure-http
Elastic Agent will be installed at /opt/Elastic/Agent and will run as a service. Do you want to continue? [Y/n]:y

```

What is " **Fleet Server - Error - failed version compatibility check with Elasticsearch: unsupported version","ecs.version":"1.6.0"**" error I do not know.

I have gone through same installation a lot of times and never I have received this error once.

Please help me how to fix it.

Hello.  
I have resolved this one. This was due to my shit knowledge and lack of work with Elastic products (just started to learn).

When installed new 8.1 version and connected with Kibana I did for some reason put http **S** \<\< in fleet server URL and then there was a problem with those versions and I guess certificates as well. Now it works for me at least. Thanks!
