I install Fleet-managed APM-Server.  
It seems active, but show error codes and doesn't work as a service.

error :  
"message":"failed to clear scroll: context deadline exceeded","service.name":"apm-server","ecs.version":"1.6.0"

"message":"refresh cache error: context deadline exceeded","service.name":"apm-server","ecs.version":"1.6.0"}

"message":"precondition failed: error querying cluster\_uuid: status\_code=401","service.name":"apm-server","ecs.version":"1.6.0"}

These 3 error codes show every seconds.

I followed this [website](https://www.elastic.co/guide/en/observability/current/get-started-with-fleet-apm-server.html)

but, it doesn't work. Please help me
