URL read error: -57

[Yetoo1]

I get a URL read error: -57 most of the time if I leave it running too long, sometimes if I refresh the url (with port included) specified in server2.c. This also sometimes occurs if the browser download prompt is cancelled. This happened sporadically as it happens almost every other time I test. Sometimes, while not downloading, the error just occurs while the tab wasn't open. When this error occurs, the server shutsdown and needs to be restarted. I was testing this on a Firefox client on installed on Windows 7 and the server is FreeBSD 12.0 where the executable was compiled as well.

This is some of the output I get before the error occurs. The error -54 error you see is due to cancelling the download prompt:

EDIT: I tested streaming with VLC and it gave the error after jumping forward in time while streaming.
