Cannot fetch hosts : [security_exception] missing authentication credentials

[igortin]

hi,
Can anybody help to solve the problem in Logtrail:
Cannot fetch hosts : [security_exception] missing authentication credentials for REST request [/logstash-*/_search], with { header={ WWW-Authenticate="Basic realm="security" charset="UTF-8"" } }

Questions:

• Do i need to configure login/password in logtrail?
• How to configure credentials in logtrail?

EFK:
elastcisearch - v7.4.0
kibana - v7.4.0
logtrail - logtrail-7.4.0-0.1.31.zip

Kibana: credentials was configured, i can get templates and etc, but i didn't check data, elastic is empty.
