Can not get details of ELK stack monitoring


Suddenly I got this error "Monitoring Request Error

Connection error: Check the Elasticsearch Monitoring cluster network connection and refer to the Kibana logs for more information.

HTTP 503"

What would be the issue? since I have not been done changes.

Did you check the Kibana logs? Please look at the logs and share them here.

Since I am new to ELK con you guide me on how to get them as required?

I can see this error when checking Kibana service status:

We were able to identify this error came because of certificate expiration, all certificates which have ES and Kibana servers have expired.
