My configuration: {{{ location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host links.x-way.org; proxy_pass https://77.37.18.97/; } }}} Sample log entries: {{{ ==> /var/log/nginx/links.x-way.org.error.log <== 2013/01/07 17:17:47 [error] 18026#0: *384 connect() failed (110: Connection timed out) while connecting to upstream, client: 216.151.139.39, server: links.x-way.org, request: ""GET /register.php/ HTTP/1.0"", upstream: ""https://77.37.18.97:0/r egister.php/"", host: ""links.x-way.org"", referrer: ""https://www.links.x-way.org/about.php/"" ==> /var/log/nginx/links.x-way.org.access.log <== 216.151.139.39 - - [07/Jan/2013:17:17:47 +0100] ""GET /register.php/ HTTP/1.0"" 502 568 ""https://www.links.x-way.org/about.php/"" ""Mozilla/5.0 (Windows NT 6.0) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.112 Safari/535.1"" 21.827 }}} From the log file we see that it is using port '0' to access the 77.37.18.97 backend instead of port '443' (for https). When explicitely specifing '443' as port in the proxy_pass directive like below, the connection to the backend works fine. {{{ location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host links.x-way.org; proxy_pass https://77.37.18.97:443/; } }}} So I guess, the problem is that the default port for the proxy_pass directive is no longer properly set (eg. 80 when proxy_pass starts with http:// and 443 when it starts with https://).",defect,closed,major,,nginx-core,1.3.x,fixed,,,Linux real.jaggi.info 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux,"nginx version: nginx/1.3.10 TLS SNI support enabled configure arguments: --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi -- http-scgi-temp-path=/var/lib/nginx/scgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --with-debug --with-http_addition_module --with-htt p_dav_module --with-http_flv_module --with-http_geoip_module --with-http_gzip_static_module --with-http_realip_module --with-http_perl_module --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-ipv6 --with-ma il --with-mail_ssl_module --add-module=/root/naxsi-core-0.49/naxsi_src --add-module=/root/src/nginx-1.3.10/modules/nginx-upstream-fair --add-module=/root/src/nginx-1.3.10/modules/ngx_http_subs_filter_module --add-module=/root/src/nginx-1.3. 10/modules/ngx_devel_kit --add-module=/root/src/nginx-1.3.10/modules/ngx_http_set_misc_module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_auth_request_module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_headers_more_filter_ module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_form_input_module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_encrypted_session_module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_echo_module --add-module=/root/ src/nginx-1.3.10/modules/ngx_http_set_hash_module --add-module=/root/src/nginx-1.3.10/modules/ngx_http_auth_pam_module --add-module=/root/my_ngx_modules/ngx_http_remote_passwd --add-module=/root/my_ngx_modules/ngx_http_filter_header"
