Cant upload files..

I am new to this kinda, im not sure if i should open up a port or 2 in my settings.. but anyways, i start uploading the 315mb file to the server, and abbout 40mb in, it stops and wont retry/start again.

i can delete it and have it do it again, upload around 40mb and stop/disconnect.

here is the log:
