I configured apache server for few sites. All works perfectly in local network.
But when I try to download files from external network - there are some problems.
I can download file only if it size is no more then 255 bytes.

Code:
wget http://128.0.24.242/README.md
--2019-06-28 20:21:06--  http://128.0.24.242/README.md
Connecting to 128.0.24.242:80... connected.
HTTP request sent, awaiting response... 200 OK

Saving to: ‘README.md.3’

README.md.3                                               0%[                                                                                                                              ]       0  --.-KB/s    in 0s      

2019-06-28 20:21:06 (0.00 B/s) - Connection closed at byte 0. Retrying.
And all works it file has size less then 256 bytes:

wget http://128.0.24.242/README2.md

Can anyone help with this? I have no idea what is wrong. Disabling firewall didn't help
