Hello I'm trying to restore my production database in my testing server.

The database size is 250Mb. In testing server, I'm using Nginx reverse proxy. I already set the max upload size to be 500Mb.

Now when I try to restore that database I get Database restore error message.

in my log file I got

2017-07-05 14:45:08,690 1480 INFO ? werkzeug: 127.0.0.1 - - [05/Jul/2017 14:45:08] "POST /web/database/restore HTTP/1.0" 200 - 
2017-07-05 14:45:09,414 2975 INFO ? werkzeug: 127.0.0.1 - - [05/Jul/2017 14:45:09] "GET /web/static/lib/bootstrap/css/bootstrap.css.map HTTP/1.0" 404 -

 However I could restore the same database in another server only without Nginx reverse proxy

Can anyone help me to figure out how to fix this problem and what's causing it? 

Thanks
