I deployed an Application to AWS elastic beanstalk. When I try to open the application, I am getting 502 proxy error Saying following message.
Proxy Error
The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /.
Reason: Error reading from remote server
Apache/2.2.31 (Amazon) Server at mehe.us-west-2.elasticbeanstalk.com Port 80
Strange part is when I run the application from localhost(Still connected to amazon database) the application is working fine, but after deloying it is not working. Here's the link to application
Any ideas how to get rid off it.
The timeout value for HTTPD is lower than the timeout value set for ELB. Change the timeout value in /etc/httpd/conf/httpd.conf
The keep the value between reboots you'll need to either create a custom AMI or use .ebextensions feature.
