I was able to deploy everything as described but Kibana keeps asking me for login and password while trying to access it thought localhost:5601.
Can you please advice ?

Thanks.

I execute the command

docker-compose up -d

and I get an error

Recently, I deployed a docker-compose-efk environment. At the beginning it could work normally, but the fluentd could not send logs to the elasticsearch next day. After I restart the fluentd container, it was normal. Unfortunately, It was wrong yet next day. I cannot find the reason. Who can help me?

Could you assist me how do I create a visualize dashboard
