Proxy Error 502 “Reason: Error reading from remote server” with Apache 2.2.3
I had a setup of tomcat running on port 8080 and Apache proxying for tomcat on port 80. If I tried to access webapps directly from tomcat on port 8080,. they were accessible, while on port 80, I would get the followig error: Proxy Error 502 “Reason: Error reading from remote server” with Apache 2.2.3 following fix worked: adding retry=1 acquire=3000 timeout=600 Keepalive=On after the Proxy directive in the http configuration.
