I'm getting an error of "gateway timeout. The gateway did not receive a timely response from the upstream server or application." What I'm doing is I'm getting data from sticky CRM by API and storing it into my database and it takes much time to execute. What I noticed is that I'm getting this error right after one minute. So I want to increase that time. I have install web server under ec2 instance and database under rds. I want to increase my gateway time from one minute to infinite or 15-20 minutes.

Help will be appreciated. Thanks.
