Faraday net_http_persistent not working in Phusion Passenger

[Jack Ocampo]

Basic info:

• Faraday Version: 0.15.4
• Ruby Version: 2.5.0
• Passenger: 6.0.2

Issue description:

Good day mga ka Ruby guys,

I have a rails app with api endpoint that will authenticate to the remote server by using api_key in order to authorized the current user.
This endpoint is using Faraday to connect to the remote server. See example below:

 HEADERS = {
      'X-Version' => 'V1',
      'X-API-Key' => 123456,
      'Content-Type' =>'application/json'
}
uri = "https://api.remoteserver.com/VerifyAPIKey"
conn = Faraday.new() do |f|
   f.adapter :net_http_persistent do |http|  
   http.idle_timeout = 100
 end
end
@response = conn.post do |req|
  req.url URI(uri)
  req.headers = HEADERS
  req.body = body
end

If you notice, I configure the adapter of Faraday using net_http_persistent because I'm running an open-source Phusion Passenger server and we need a persistent connection because the Passenger is a multi-process which means it will spawn one or more processes as the load increases. However at first request the api was successfully authorized(see processID #26698) but on the next request I got authorization error (processID #64121)
See the logs below:
I, [2019-04-01T18:20:29.611996 #26698] INFO -- Authorization is finished successfully.
I, [2019-04-01T18:20:29.611996 #26698] INFO Thread with name "MsgsQueue worker #47338607938600"

I, [2019-04-01T23:20:09.341415 #64121] INFO Thread with name "LogsSender worker #42158391867991" is terminated!

Is there any settings in Faraday that I'm missing ?
Any help would be greatly appreciated. Thanks

Your Rails app is the one you're trying to authenticate with? Or your Rails app makes a call to another Rails app with Phusion?

Try making this call with something like Postman or just plain curl first.
