HI;

I’m using Nginx in a reverse proxy setup with Apache. I’m having a  
problem when I submit a large upload via php; while Mogrify is  
processing the photo upload, Nginx returns a 504 error - Gateway  
Timeout.

I tried adding in proxy\_read\_timeout 600; proxy\_send\_timeout 600;, but  
I am still having the same problem.

I’ve searched for answers for quite a few hours now, and am at a loss.  
All of my PHP memory and time out settings are quite high.

It works when I do smaller uploads. It is the ones that take Mogrify  
more than about 60 to 90 seconds to process that cause the error.  
(uploads of over about 50 MB of images).

I was able to upload / process with this system prior to installing  
Nginx. Please let me know if you want to see a copy of my config file  
or any other information.

Thank You Kindly;

Jamie

I added the above proxy read and proxy send lines. I had just  
reinstalled this morning after doing some testing and accidentally  
sent you the file without those added.

Thanks,

Jamie

Fine. But please note, this is only part of configuration. There are  
some files regarding to directive:  
/etc/nginx/vhosts/\*

Please include them also.

file upload size or php max running time.

Hi guys,

I have the exactly same issue.  
What about include proxy.inc ?

Those are my values :  
proxy\_connect\_timeout 90;  
proxy\_send\_timeout 90;  
proxy\_read\_timeout 90;  
proxy\_buffer\_size 4k;  
proxy\_buffers 4 32k;  
proxy\_busy\_buffers\_size 64k;  
proxy\_temp\_file\_write\_size 64k;

Use it with Magento on a VPS and always need to restart APACHE

Thanks for the help,

Antoine
