Kibana: getting 503 "service unavailable"

Hello guys,

I am working on kibana 8.1.2 version.
while creating/updating charts and loading dashboard I am getting 503 "service unavailable" message.

Can anyone please help me to understand this issue?

Thanks

check Elasticsearch status. Elasticsearch needs to be up and running

It'd be useful if you could post your Kibana logs.

it is up and running

yeah will upload logs here

due to security reasons I can not paste full logs here.

there are 3 errors,

  1. ResponseError: circuit_breaking_exception: [circuit_breaking_exception] Reason: [parent] Data too large, data for [<http_request>] would be [2042528968/1.9gb], which is larger than the limit of [2040109465/1.8gb], real usage: [2042528968/1.9gb], new bytes reserved: [0/0b], usages [request=882917432/842mb, fielddata=725/725b, eql_sequence=0/0b, model_inference=0/0b, inflight_requests=0/0b]

  2. License is not available, authentication is not possible.

  3. ResponseError: security_exception: [security_exception] Reason: action [indices:data/read/search] is unauthorized for user [usr] with roles [kibana_system,kibana_admin,monitoring_user,superuser], this action is granted by the index privileges [read,all]

the 3rd error is also logged for superuser but from kibana UI have not got any unauthorized error. In addition to this, I believe superuser has full access of cluster so how come unauthorized error occur?

I hope this details will help
