not sure if this is actually an apache issue or config issue.
i have a setup with a server which is behind a load balancer.
the server has apache 2.4.6 and running
os: Red Hat Enterprise Linux Server release 7.1 (Maipo)
apache has a bunch of defined urls which are then going to a backend which is written in nodejs
and the issue is when uploading "larger" files (20mb+), funny enough this doesn't occur on my test server which is essentially the same in everyway just with no load.i get the following error.
error
Bad Gateway The proxy server received an invalid response from an upstream server.
