you want to serve your application through a UNIX domain socket (to serve a downstream HTTP server/proxy such as nginx, lighttpd, and so on), call serve with the unix_socket argument: from waitress import --listen "*:$PORT" \ --trusted-proxy '*' \ --trusted-proxy-headers 'x-forwarded-for x-forwarded-proto x-forwarded-port' \ --log-untrusted-proxy-headers \ --clear-untrusted-proxy-headers \ --threads ${WEB_CONCURRENCY:-4} ${WEB_CONCURRENCY:-4} \ myapp:wsgifunc The proxy config informs Waitress to trust the forwarding headers set by the Heroku load balancer. It also allows for setting the standard WEB_CONCURRENCY environment
