As shown in the screenshot , I’m having this issue . I tried a fresh installation and again after running for few days , I got this error again. I did some research and found that the roles for the kibana_system user is removed automatically and can’t be assigned manually . I don’t know if this is the exact issue or something else .
Please help me to resolve this error.
Now I got to know that it’s working on some laptops but not working on the others. I tried clearing the cache , changing the browsers and restarting the services . But the issue is persist for all laptops except a few.
8.11 is very old. Is there a chance that you can upgrade to at least 8.19.14 or better 9.3.3 version?
