Kibana UI Dashboard Access Issue

Unable to Access Kibana UI Dashboard Getting Below Error, Getting Please upgrade browser in Google Chrome/Edge/Firefox

Kibana - 8.3.3
Elasticsearch - 8.3.3

No Domain Mapped Trying to Access using kibana-ip:5601

Hi @Money welcome to the community.

How did you install Kibana and Elastic?
Are you sure elastic is running this error is Usually when Kibana can not Communicate with Elasticsearch

From the server your kibana is running on ... or from this desktop

curl -v -k -u elastic https://<elasticip>:9200

Hi @stephenb,

Thanks for your promptness

I am Running Kibana and Elasticsearch in Centos 8 Stream Linux Server

As Mentioned Below is the Screenshot of the curl command, Please check once

Please don't post pictures of text...also.please show the exact command that was run.

Is Elasticsearch configured with security/ SSL

You can see the connection / SSL failed...

Seems like perhaps the server has old SSL./ TLS ...

Hi @stephenb,

Thanks for your Time, sorry security was disabled by me at the time of troubleshooting, I have enabled security after your Reply below is the text output from curl command

I am Unable to Access the Kibana Dashboard from Any Browser because of CSP Error

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'unsafe-eval'". Either the 'unsafe-inline' keyword, a hash ('sha256-P5polb1UreUSOe5V/Pv7tc+yeZuJXiOi/3fqhGsU7BE='), or a nonce ('nonce-...') is required to enable inline execution.


Yeah I don't think that browser error is the issue.

The Kibana Server Not Ready Yet error Is generally the Kibana server cannot connect to elasticsearch server.

You are going need to look at the Kibana Logs and perhaps share you Kibana.yml

Hi @stephenb,

Please find below

You should definitely set saved Objects encryption key but that should not stop Kibana..

Perhaps look at the Kibana logs when you reload Kibana in the Browser.

You can see that resulted in a 503

Of course your picture on top shows http not https. So did you restart Kibana after you fix the settings??

I would tail the logs from the time you start Kibana and look for errors

You can also try setting this to none to test and debug

Hi @stephenb,

Yes, I am trying for HTTP only getting a service unavailable error from the Browser Inpect/Network/Headers I found this.

Hi @stephenb,

I have Added in Kibana.yml seems like i am Getting request timedout in kibana.log from earlier also

Hello @stephenb,

Thanks for your time, I have Resolved the issue by changing Elasticsearch IPV4 Address to localhost in the kibana.yml file, and working fine now.

Thanks & Regards.
