502 bad gateway error from haproxy

[Arun Maha]

I am using openshift 4.5. I used service and routes and it is externally accessible. Application is working fine, but sometimes i am getting 502 error. I am using haproxy  ingress routes. When does haproxy ingress return 502 error?

 Appreciate your thoughts on resolving this issue.

From haproxy doc -
http://cbonte.github.io/haproxy-dconv/2.2/configuration.html#1.3.1

502 when the server returns an empty, invalid or incomplete response, or
when an "http-response deny" rule blocks the response.
