I was using ELK 8.4 and everything was working fine until I saw pending updates on the server which included Elastic and Kibana 8.5 updates.
AND after upgrading both services are in active running status but kibana giving this error
Kibana server is not ready yet
I'm clueless, please help
@warkolm where you at sir?
Check kibana.log
kibana.log

Timeout waiting for the status
Do you have enough disk space? Is your ES stable?
When last time ELK was running properly, disk storage used was 91%
and then IT updated the server and since yesterday I'm unable to start ELK
elastic 9200 shows this
"cluster_name" : "elasticsearch",
"cluster_uuid" : "*******",
"version" : {
"number" : "8.5.2",
"build_flavor" : "default",
"build_type" : "deb",
"build_hash" : "*********",
"build_date" : "2022-11-17T18:56:17.538630285Z",
"build_snapshot" : false,
"lucene_version" : "9.4.1",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}```
and kibana url shows
Kibana server is not ready yet.Not enough disk space. Keep it below 85%
Yea I did some R and D and deleted some old indices via post request and freed some storage which actually started the kibana UI and now when I'm trying to access the fleet section I'm getting this error
except this all other tabs are working and logs are also coming via elastic agent
Please don't @ people that aren't already helping
