I have ES 7.6.2 installed on my AWS EC2 Ubuntu instance and it was working perfectly fine from months. Today i updated some security Ubuntu packages and after that the PHP client is getting timed out in most of the cases.
Please note that i am able to connect every-time via Curl & Kibana which are residing on that same server.
Elastic search is configured on localhost.
The strange part is that almost 10% of hits getting successful connection but fails 90% and gets timed out when trying using PHP client.
All requests via CURL & Kibana successfully connected every-time.
Not sure what has changed after those security updates on EC2
Can anyone please help?
