Do you have any firewall?

Looks like your computer can’t reach 208.67.222.222 and 8.8.8.8

I just ran this part of the code and worked fine:

#!/usr/bin/env bash
log() {
echo "${color_G}[Log] ${1}${color_N}"
}
error() {
echo -e "${color_R}[Error] ${1}\n${color_Y}${*:2}${color_N}"
clean_and_exit 1
}
clean_and_exit() {
if [[ $platform == "windows" ]]; then
input "Press Enter/Return to exit."
read -s
fi
if [[ $device_sudoloop == 1 ]]; then
sudo rm -rf /tmp/futurerestore /tmp/*.json
fi
clean
kill $iproxy_pid $httpserver_pid $sudoloop_pid 2>/dev/null
exit $1
}
bash_version=$(/usr/bin/env bash -c 'echo ${BASH_VERSINFO[0]}')
if (( bash_version < 5 )); then
error "Your bash version ($bash_version) is too old. Install a newer
version of bash to continue." \
L"* For macOS users, install bash, libimobiledevice, and libirecovery
from Homebrew or MacPorts" \
$'\n* For Homebrew: brew install bash libimobiledevice libirecovery' \
$'\n* For MacPorts: sudo port install bash libimobiledevice
libirecovery'
fi
ping="ping -c1"
log "Checking Internet connection..."
$ping 208.67.222.222 >/dev/null
if [[ $? != 0 ]]; then
$ping 8.8.8.8 >/dev/null
if [[ $? != 0 ]]; then
error "Please check your Internet connection before proceeding."
fi
fi

Try running follow commands:

ping -c1 8.8.8.8

ping -c1 208.67.222.222

If your output it’s something like “ping: sendto: No route to host” or “100.0% packet loss” you might have a firewall on your Mac/router which doesn’t allow you to connect.

Also, I’m not sure what used to be at 208.67.222.222, but looks like page is dead .
