The 504 issue can perhaps be fixed with increasing php max_execution_time and/or max_input_time. You can also try increasing proxy_read_timeout or fastcgi_read_timeout depending on how you are serving php requests. You can find info on these at http://wiki.nginx.org/NginxHttpProxyModule#proxy_read_timeout and http://wiki.nginx.org/NginxHttpFcgiModule#fastcgi_read_timeout.

The upload progress bar will not work if it's based on the Uber Uploader. I'm not exactly sure why but I believe it has to do with requiring keepalive connections to the backend which nginx does not support as yet. Nginx supports HTTP 1.1 when "speaking" to the client but "speaks" HTTP 1.0 to the backend.

Despite this, the files should still upload.

You have three choices.
[list=1]
[*] Don't use nginx
[*] Edit the script to change the error message, perhaps using an animated gif to let users know that upload is in progress
[*] Use the upload progress bar written for nginx which will probably require a fair bit of rewriting of your app
[/list]

too bad i was left with option to remove Nginx , but i do hope that i will see a day when nginx supports upload bars :)

The plan is to introduce keepalive connections to the backend in the 0.8 branch at some point (in other words HTTP 1.1). Since 0.8.0 was just released yesterday it could be awhile before that happens. Of course once that happens there is still no guarantee that Uber Uploader will function correctly.

Some upload progress meters work fine with nginx. It simply depends on how they are written.

hi just wondering is there an update on fixing this issue? i am having the same problem as bhanuprasad1981

what upload progress meters work with nginx? I was using uber uploader but since that doesn't work I'd like a new solution.
