Can't download helper-scripts

[fl5x]

Well, first of all, it is a fresh install and sometimes it works, I mean, if I run:

# wget https://github.com/tteck/Proxmox/raw/main/misc/post-pbs-install.sh

I get:

But most of the time, this is what I get:

--2024-09-14 20:07:29--  https://github.com/tteck/Proxmox/raw/main/misc/post-pbs-install.sh

I have copied the scripts to another server I have and it always works. So I guess it not a hardware or software problem on my end, right?

Isn't it weird?
