[alexus]

I'm Running Kibana on Docker and seeing quite a lot following message in my logs:

Unable to fetch data from kibana collector

Please advise.

Unable to fetch data from kibana

Hey @alexus, is there an error printed before you see this message?

[alexus]

my logs are flooded with that message, one after another...

[Brandon_Kobel]

@alexus which version of Kibana are you running?

[alexus]

6.3.1

Hi @alexus,

Can you double check the log or paste the entire log in here? From reading the code, the error should be logged as well.

Seeing this in 6.3.2 as well:
