How are you creating your index pattern and did you also create an index pattern template? @Pierre_Gayvallet how do we fix this? Thanks, Bhavya ---

@bhavyarm Yes, We have created index templates and gave the index patterns to apply to that template. Also, We are using Data Streams instead of indices. Any inputs on resolving this is much appreciated. Thanks. ---

@Avinash_09 - Did you happen to disable `index.refresh_interval` (i.e value = `-1`). We have seen similar errors in the past where the refresh interval was disabled on the `.security-tokens-7` , `.security-7` or `.kibana_security_session_1` indices and this would result into similar issues. I would recommend to check these indices settings (c.f `GET .kibana_security_session_1/_settings`, etc.) ---

Hi @ropc , No, We haven't disabled any refresh interval settings on these indices in our environment. We have recently upgraded the Elastic stack to 8.3.3 to overcome this issue. But, Post upgrade, When checked about this indices, For .kibana\_security\_session\_1, .security-7 indices the refresh interval is with 1s and there is no index named .security-tokens-7. Getting below message in dev-tools: ''' "type": "index\_not\_found\_exception", "reason": "no such index [.security-tokens-7]" ''' What could be the next steps to resolve this issue? Can re-install of kibana nodes and joining them to existing elastic cluster would help? If yes, Should we need to follow any pre-steps before re-install of kibana to avoid any data loss w.r.t kibana related indices. Regards, Avinash ---

Getting below message in dev-tools The `.security-tokens-7` index will only exists if you have authentication realms where access tokens need to be stored (e.g SAML authentication realm). ---

Hi @ropc, Thanks for the quick reply. But, Post upgrade also we are still seeing the issue intermittently when accessing with kibana internal URL. Along with that, We are having new issue when accessing the Kibana via proxy/public URL. Below is the error message: ## Please upgrade your browser This Elastic installation has strict security requirements enabled that your current browser does not meet PFA screenshot for the same. ![Kibana](https://us1.discourse-cdn.com/elastic/original/3X/e/5/e54ccdddfdb8ba990197cdf17614a1558f43d027.png) Can you please help us here.

Yes @ropc, To your question 1: Yes, I am referring the same error. Yes, We have 2 kibana instances running for this cluster. Any other places to check on this issue? Thanks for info on point 2. I will check on Content Security Policy (CSP) settings and see if the browser outdated issue gets resolved. Regards, Avinash ---

> To your question 1: Yes, I am referring the same error. Yes, We have 2 kibana instances running for this cluster. Any other places to check on this issue? Is this proxy used as a load-balancer as well? Perhaps you may want to check the following documentation: - [Load balancing across multiple Kibana instances](https://www.elastic.co/guide/en/kibana/current/production.html#load-balancing-kibana) - [Accessing multiple load-balanced Kibana clusters](https://www.elastic.co/guide/en/kibana/current/production.html#accessing-load-balanced-kibana) ---

Hi @ropc, Yes, Proxy is used as load balancer. We have followed the necessary steps as per documentation. But, Will cross check on them and get back. w.r.t browser issue (Content Security Policy), even after applying the settings still we see the same info message on browser. ## Please upgrade your browser This Elastic installation has strict security requirements enabled that your current browser does not meet.

1. What is the current setting in Kibana for `csp.strict` and are you facing this issue on all browsers? Which browser / browser version are you using? 2. Have you tried to bypass the proxy and check if the same problem happens? ---

If bypassing the proxy works, then it must be something related to the proxy and its configuration. This is not really my expertise but I can ask around... Which proxy are you using? ---

@ropc, Thanks for the update. We suspect the same. We are using Apache httpd as proxy server. Can you check and update us w.r.t the changes need to be done on Proxy server to fix this issue? ---

@Avinash_09 - One thing I can think about is the Apache httpd server overriding the `Content-Security-Policy` header. It is a wild guess but you may want to check with your IT team if any headers are being overridden at the proxy level. ---

@Avinash_09 - I am not sure as well - you would need to cross-reference the Kibana logs with the authentication issue. If this issue is reproducible, a HAR file capturing the issue along with the Kibana logs would usually help. However, it will be best if you can get this issue reviewed by our Support team (if you do have a subscription with us).
