I have an Apache config which works perfectly, and tried to emulate it in nginx, however it only partially works. The first location /authenticate/ { } directive works fine, but the second location /cas/ { } directive times out, causing nginx to return an error to the browser. From the command line on the server I can manually retrieve http://10.8.120.10:5447/ with no difficulty, and as mentioned, the apache config works perfectly.

Apache Config:

Any insight into any errors I might have in my nginx config would be greatly appreciated, or if there is a deeper problem in nginx that I can explore. Thanks!
