server errors AWS

HTTP 502 (bad gateway) errors can occur for one of the following reasons: The web server or associated back end application servers running on EC2 instances return a message that can't be parsed by the Classic Load Balancer. The web server or associated back end application servers return a 502 error message of their own. To find the source of these 502 errors: Need to enable ELB access logs on Classic Load Balancer to see the backend and Elastic Load Balancing (ELB) response code for each request. An access log entry contains two fields: an elb_status_code and a backend_status_code. Need to view the load balancer CloudWatch metrics to see backend-generated 502 errors, which appear under the HTTPCode_Backend_5XX metric. If the backend response is the source of the 502 error, the issue might be caused by: A response containing more than one CRLF between each header. A response containing a Content-Length header which contains a non-integer. A response has more bytes in the body than the Content-Length header value. Basically need to find the source of the 502 error issues; To fix it need to confirm that the response header has the correct syntax: a key and the value, such as Content-Type:text. Be sure that Content-Length or transfer encoding is not missed in the HTTP response header. Please ping me to have a discussion on your convenient time; Looking forward to have a positive response by your end;
