504 Gateway Timeout ELB

This is my current project set up.



Client --> AWS ELB (Classic) -->Node Js ---> AWS ELB (Classic) --> Tomcat (Java Application)



I have the AWS ELB's idle time out configured to 600 seconds across all the instances. Also nodeJS server timeouts are set to 600 seconds using server.setTimeout() .



When i execute a request from the browser after around two minutes i get a 504 Gateway Timeout error.



After researching online and following suggestions i was able to narrow down the problem to AWS ELB connecting to the Node JS. Also turning ELB logs did not yield any exceptions to pinpoint the problem .



My client code is react based and we use request (http) library to make the connections to node.js . No where in the client code we set the timeout in http calls.



  1. Why does the ELB times out after 2 minutes in spite of having the idle timeout set at 600 seconds (10 minutes)?


  2. Where else should i look for the 2 minute timeout setting in the above set up? Does the request library have any default timeout?
