How i can solve this issue?

did you enable security in elasticsearch.yml?
elasticsearch.yml

xpack.security.transport.ssl.enabled: true
xpack.security.enabled: true
xpack.security.authc:
 anonymous:
  username: anonymous_user
  roles: role1, role2
  authz_exception: true

did you create passwords for elasticsearch build-in users?
./bin/elasticsearch-setup-passwords interactive

Add build-in users to kibana,

./bin/kibana-keystore create
./bin/kibana-keystore add elasticsearch.username
./bin/kibana-keystore add elasticsearch.password

[emilio]

No.
Only this one is configured in elasticsearch.yml

What is the need to configure anonymous_user in elasticsearch.yml?

I have created users for built-in users using ./bin/elasticsearch-setup-passwords interactive.

I have defined elasticsearch.username and elasticsearch.password explicitly
