Hello,
I have been running into an issue with my Kibana dashboard. Currently, it shows "Kibana server is not ready yet". When I use the journalctl -xe command, I see the following error for Kibana:
["warning","plugins","licensing"],"pid":6937,"message":"License information could not be obtained from Elasticsearch due to [security_exception] unable to authenticate user [kibana] for REST request [/_xpack], with { header={ WWW-Authenticate=\"Basic realm=\\\"security\\\" charset=\\\"UTF-8\\\"\" } }
It sounds like there is some sort of authentication error. I had setup the elasticsearch-setup-passwords tool before and everything had been working correctly before. But since I had setup the passwords for the elastic users prior to this issue, I am unable to reset those passwords. I tried using the elasticsearch-users passwd function and get the following error:
ERROR: Invalid username [elastic]... Username [elastic] is reserved and may not be used.
I get this error regardless of user (elastic, kibana, etc). I should note that this issue started occuring when I removed all prior indices to free space. The partition I had for the indices filled up very quickly and caused Elasticsearch and Kibana to crash. I should also note that I am unable to authenticate using cURL
curl -u elastic'http://localhost:9200/_xpack/security/_authenticate?pretty'
Result:
{
"error" : {
"root_cause" : [
{
"type" : "security_exception",
"reason" : "unable to authenticate user [elastic] for REST request [/_xpack/security/_authenticate?pretty]",
"header" : {
"WWW-Authenticate" : "Basic realm="security" charset="UTF-8""
}
}
],
"type" : "security_exception",
"reason" : "unable to authenticate user [elastic] for REST request [/_xpack/security/_authenticate?pretty]",
"header" : {
"WWW-Authenticate" : "Basic realm="security" charset="UTF-8""
}
},
"status" : 401
}
Is there anyway I can fix this error? Would I have to re-setup the passwords for the elastic users? I am running Elasticsearch Version 7.9.2
Thank you for any and all help
