Actual behaviour
When Owncloud client sync files from server to computer (downloading ~ 5 gb files) after few seconds i have Connection closed / Operation cancelled :confused: but when I upload files to server (it does not matter if many small or one big files) sync works fine without problems.

I was looking for a solution in all other threads but I did't find.

This problem is only when I download files, uploads works fine and I don't know why. Probably in apache php configuration but the logs on server side are clean.

I changed the server from apache to nginx and owncloud works fine without problem.
I tried to lookup when in my apache config is mistake.

Could be because you used PHP FPM?

FYI @PVince81 @DeepDiver1975 nginx worked, Apache didn't.. something bogus with Apache to keep in mind

6

With nginx I use php-fpm too and works fine.

I tried to change php config with apache fcgi or cli but I did't get the expected results.

I recommend nginx for owncloud :wink:

Most likely. There are quite a few bugs and issues out there which are known if Apache is used with php-fpm or fastcgi ([1], [2] and [3]) and which are not happening if using Apache + mod_php or nginx + php-fpm.
