Upstream: don't consider default_port when matching upstreams. The only thing that default_port comparison did in the current code is prevented implicit upstreams to the same address/port from being aliased for http and https, e.g.: proxy_pass http://10.0.0.1:12345; proxy_pass https://10.0.0.1:12345; This is inconsistent because it doesn't work for a similar case with uswgi_pass: uwsgi_pass uwsgi://10.0.0.1:12345; uwsgi_pass suwsgi://10.0.0.1:12345; or with an explicit upstream: upstream u { server 10.0.0.1:12345; } proxy_pass http://u; proxy_pass https://u; Before c9059bd5445b, default_port comparison was needed to differentiate implicit upstreams in proxy_pass http://example.com; and proxy_pass https://example.com; as u->port was not set.
