I have a SoYouStart dedicated server with Proxmox 5.2 installed

I'm failing to upload files to guest webservers, the upload is stuck at around 10~12 seconds after starting, at my connection speed a 10 MB file takes around 18 seconds to get uploaded, i could never finish it.

on a faster connection, 10 MB got uploaded but bigger file didn't. I also tried a 3MB file from my connection with chrome throttling the connection and it also stops at around 10 to 13 seconds.

my server environment: dedicated server with proxmox 5, create an CT with ubuntu 18.04. installed apache2, php7.2.

I changed the php configuration to support bigger files:

upload_max_filesize = 200MB
post_max_size = 210MB
max_execution_time = 60
max_input_time = 60
memory_limit = 256M

I'm also not getting any error in apache access.log or error.log

I also tried different configuration:

ubuntu on dedicated without proxmox, it worked
proxmox + CT (ubuntu 18.04+apache2+php7.2) not working
proxmox + CT (ubuntu 18.04+lighttpd+php7.2) not working
proxmox + CT (ubuntu 17.10+apache2+php7.2) not working
proxmox + CT (Centos 7+apache2+php5.4) not working
proxmox + VM (Ubuntu 18.04+apache2+php7.2) not working

I tried having the same upload script and apache2 config on the host directly, it worked.
