I'm trying to enroll an agent using fleet, but seems there is something wrong with the api\_key.
Is there a was how to initiate again the fleet setup (including user and role)?
How could be below mentioned error be solved?
Latest version 7.10.2 is used.
Details:
When starting an agent with fleet enroll:
```auto
Error: fail to enroll: fail to execute request to Kibana: Status code: 400, Kibana returned an error: Bad Request, message: Fleet Admin user is invalid: [security_exception] unable to authenticate user [fleet_enroll] for REST request [/_security/api_key], with { header={ WWW-Authenticate={ 0="Basic realm=\"security\" charset=\"UTF-8\"" & 1="Bearer realm=\"security\"" & 2="ApiKey" } } }
Error: enroll command failed with exit code: 1
```
When generating new enrollment token following error appears:
```auto
Fleet Admin user is invalid: [security_exception] unable to authenticate user [fleet_enroll] for REST request [/_security/api_key], with { header={ WWW-Authenticate={ 0="Basic realm=\"security\" charset=\"UTF-8\"" & 1="Bearer realm=\"security\"" & 2="ApiKey" } } }
```
Thanks!

Hey @Robo ,
You can probably fix this by removing the default output
```auto
POST /.kibana/_delete_by_query
{
"query": {
"bool": {
"must": [
{
"terms": {
"type": [
"ingest-outputs"
]
}
}
]
}
}
}
```
Then restarting Kibana and setup Fleet again from the UI should do the job.
Best,
Oleg

Thanks! Work as a charm. Also agent enrollment is working now without issues.
Maybe this can be added into common problems troubleshooting.

Glad it helped! That's a good idea, let me check with the relevant team if they can include this.
