I just installed Debian. I was trying to install ProtonVpn but I can't pull the deb file with wget

I just installed Debian. I was trying to install ProtonVpn but I can't pull the deb file with wget. My system clock is up to date. I also tried adding different servers in the resolve.conf file but the problem persists.The connection is established but the rest does not work. My system information:

uname -a
    Linux localhost 6.1.0-31-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.128-1 (2025-02-07) x86_64 GNU/Linux

I tried to reinstall my certificates but it didn't work. Moreover

add-apt-repository 'deb https://protonvpn.com/download/debian  stable main'

is not working, here is same error:

...
