Upgraded ELK stack to 7.1 and now kibana is stuck at loading

[Tom Astle]

I upgraded Wazuh to 3.9 and the ELK stack to 7.1 from 6.9 ( i think) 

Now I am unable to get the kibana UI to load.  I am seeing a lot of 304 errors in the kibana log. But other than that no other errors.

I am at a loss as to what to do from here.

Hi Tom,

We're going to collect as much data as possible to try to find the problem. It is possible that your Easticsearch or Kibana services are in a failed state. Could you execute and paste the output of the commands below:

systemctl status elasticsearch -l

systemctl status kibana -l

Could you paste here the logs you’re getting from Kibana? And the logs of Elasticsearch with cat /var/log/elasticsearch/my-cluster.log?

Let’s see if there’s any error log to help us identify what’s going on.

And please, can you send the content of your /etc/elasticsearch/elasticsearch.yml and your /etc/kibana/kibana.yml files?

Regards.
