Hello,

I am trying to use the complete agent as recommended by the docs, for use the browser synthetics, according this post:

> [@\[synthetics\] errors with private location with synthetics browser monitors](https://discuss.elastic.co/t/synthetics-errors-with-private-location-with-synthetics-browser-monitors/327094):
>
> Hi, I am trying to create a monitor using a private location. I am following this [procedure](https://www.elastic.co/guide/en/observability/master/synthetics-private-location.html#synthetics-private-location-fleet-agent) however, when I set up the monitor with the private location from the uptime page in kibana, I get the following error: io:job could not be initialized: browser monitors cannot be created outside the official elastic docker image as additional information I am using fleet server on elastic cloud 8.6 and an elastic agent 8.6 installed in a container in GCP virtual machine . Could you help me? thanks…

Also i have alredy everything configured fine and working, without issues, but its a normal agent, so when i use browser synthetics i receive this error:  
Job could not be initialized: browser monitors cannot be created outside the official elastic docker image

At this time i am running this command to try install the elastic complete agent from the image docker provided on the docs:

```auto
/[root@vps-testes ~]# docker run --env FLEET_ENROLL=1 --env FLEET_URL=https://MYIPHERE:9200 --env FLEET_SERVER_ELASTICSEARCH_CA=/elastic_cert/http_ca.crt --env FLEET_ENROLLMENT_TOKEN=MYTOKENHERE== --env FLEET_INSECURE=1 --cap-add=NET_RAW --cap-add=SETUID --rm docker.elastic.co/beats/elastic-agent-complete:8.8.2 -e

[root@vps-testes ~]# 

```

I was also tried used to see more verbose without successfull on verbose logs. Also in the server at /var/log/elasticsearch/elasticsearch.log or elasticsearch\_server.json dont have nothing relevant to this issue.

Thanks in advance!

Hi Igor, welcome to the community.

The error message of the `docker` command indicates that the Fleet Server API is not found, are you using the right url for `FLEET_URL`? Fleet Server is started on port 8220 by default, 9200 sounds like Elasticsearch.
