Elasticsearch plugin is red (5.2.2)

[thilina_et.lk (Thilina Nuwan)]

Hi,
I have ElasticSearch running on a remote server. I'm using kibana to access the elasticsearch. But recently i can not access the elastic through kibana or postman but elastic queries are working fine with web application, that i have created.

Kibana CMD displays that "Elasticsearch plugin is red". I did elasticsearch restart and no luck of fixing the issue.
What can i do to overcome this issue..?

What does kibana logs say?

I saw something similar once when Elasticsearch and Kibana were not the same version.

And you are running Elasticsearch 5.2.2?

A timeout error could be a network problem... Is the Elasticsearch port open from the machine running Elasticsearch to the machine running Kibana?

I have the same problem！
My elasticsearch and Kibana have the same version，5.3.1.
The Kibana is changing status between error and info for a long time, I don't know how to fix it.
Any ideas?
