If you add "-H Host:demo.domain.com " to the curl command (just after "-i "), you will more closely mimic what nginx should be doing – that might show you the correct content. > No if I do: > curl -i [http://domain.com/assets/js/msgFBmodal.js](http://domain.com/assets/js/msgFBmodal.js) > > It returns the page code from that file. I’m unsure what you mean here. If it is “now it is all working”, then that’s good and the most likely reason for the problem was that apache was not running, or was firewalled, when you first tested and that has now been fixed. If it is “here is a similar thing that is working, but my test case is not”, then can you provide enough of the nginx.conf to allow the test be reproduced? Probably, that will be just the location{} block that has the proxy\_pass that is used in the request, plus the relevant upstream{} definition if there is one, plus whatever config is in that server{} but outside all location{}s. (Or just include the whole nginx config.) Cheers, ## f Francis D. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Sorry for the grammar error. If I do curl -i [http://domain.com/assets/js/msgFBmodal.js](http://domain.com/assets/js/msgFBmodal.js) it returns the code from the msgFBmodal.js page. Yet if I hit the page via browser I still receive the gateway error.

You need to show us some commands running, some output, and nginx config - without redacted network names. This is too annoying/confusing to help you troubleshoot without seeing exactly what you’re running exactly where. Jonathan ---

Yes or no: “[domain.com](http://domain.com)” is your nginx-hosted web site, and resolves to your nginx server?

It only shows the top half of the main file; I suspect it will “include” some other files. What matters is the configuration of the server{} block that handles [domain.com](http://domain.com). ## f Francis D.
