Kibana 7.8 won't start

[Amphagory]

Hello,

I seen similar issues to mine on this forum and other sites (i.e. stack overflow), but no concrete solution. I thought I would post it again and see if someone has a solution now.

I am unable to start Kibana:

AWS t2.medium EC2 instance running Amazon Linux 2 AMI
Elasticsearch Version: 7.8
Kibana Version: kibana-7.8

kibana.yml file:
server.host: "0.0.0.0"
elasticsearch.hosts: ["https://ELASTICSEARCH_MANAGED_SERVICE:9243"]
elasticsearch.username: "elastic"
elasticsearch.password: "SECRET"
xpack.reporting.encryptionKey: "PRIVATE"

Status:

It's hard to identify the problem without any logs. Would you mind providing more info? The warnings couldn't prevent Kibana from starting

Jul 15 16:34:16 ip-172-31-22-249.us-west-1.compute.internal kibana[19313]:  {"type":"log","@timestamp":"2020-07-15T16:33:46Z","tags":["warning","plugins-discovery"],"pid":19275,"message":"Expect plugin \"id\" in camelCase, but found: apm_oss"}

Are you trying to update the Kibana version? Or you start a new project?
Do you use ElasticCloud? If so, have you tried to contact our support?

I am just installing a fresh Kibana onto an EC2 instance and starting it. No plugins or any modifications.

As for the Kibana logs, I guess I would need to install them as suggest by this page -> https://www.elastic.co/guide/en/elastic-stack-get-started/7.8/get-started-elastic-stack.html#install-kibana?

[Amphagory]

I do use the Elastic service for my Elasticsearch.

I guess I can contact them as well.

Not really, Kibana logs the most important messages out of the box. You already have provided some of them:

Jul 15 16:34:16 ip-172-31-22-249.us-west-1.compute.internal kibana[19313]:  {"type":"log","@timestamp":"2020-07-15T16:33:46Z","tags":["warning","plugins-discovery"],"pid":19275,"message":"Expect plugin \"id\" in camelCase, but found: apm_oss"}

But it doesn't look like a complete log. You should be able to find the full logs in the cloud console.
