Describe the bug

I'm having some problems trying to download videos and audio. The script hangs without throwing any error code, it just seems like the download never starts for very long time than it will works.
I have tried different versions of Python (3.12 and 3.13), different versions of pytubefix and different computers without encountering any kind of problem like bot detection and so on.
My script works fine with a virtual machine running on Kali Linux 2024.3 but doesn't work on different machines running W11 and MacOS.
I figured out how to run the script on all machines, I have to use my cell phone hotspot except for the virtual machine which works fine on the default LAN.
To recapt. On W11 and MacOS using LAN the download starts after about 4/5 minutes, on my virtual machine it's instant.
Using hotspot from other source is istant on evey platform.
Anyone have any ideas?
