Kraken does not ping cerberus for retrieving pass/fail signal

[Noreen21]

Cerberus and Kraken are installed separately. Cerberus is properly publishing cluster health status or go/no-go signal

# curl -k http://0.0.0.0:8087                                                                                                                                                                            
False

However Kraken is not able to consume that signal despite configuring the following under Krkn config file: cerberus_enabled: True cerberus_url: http://0.0.0.0:8087
