I'm not entirely sure what I should send as an image, but I made some diagnostics and found a more broad error.
The problem is not even in my computer, it's port 80 which is slow. Ran the server on port 8080 and the downloads achieve max speeds.
To wrap it up, my port 80 seems to be the only port that can't output more than 4 kbps, all the other ones can get 100 times that. I know this is not related to Laragon but I also know there are people with a lot of experience in the subject. Could this be my ISP throttling my port 80? (What I'm asking is if they have control over this).
