I found this site very slow to respond. It could be timing out with an
empty result. OTOH the URL used in the get_ip_address function is
rapid, but you don't call that function.

Yes, I notice it, it take upwards 10sec to get an IP and sometimes I
get a timeout, I increases "sleep 15" hopefully it will help.
It won't because the curl command is running synchronously. All
increasing the sleep does is make you wait longer after it fails. Why not
simply switch to the other service that seems to work more reliably?
I think this is better version:

Hmm,... do you mean i run:
NEW_IP=$(curl -s https://ifconfig.me/ip)
I tried it. When the "curl -s https://ifconfig.me/ip; failed, showing empty IP
curl -s https://ifconfig.me/ip was empty as well.

Thanks for the pointer.

[gentoo-user] ip_change_notifier - empty IP address
I run this little script to notify me when the IP changes. However at time to time the
file: "old_ip.txt"
is being populated with an empty line "no IP address"
What could be causing it?
#!/bin/bash
# Replace "YOUR_EMAIL" with your actual email address
EMAIL="your_em...@gmail.com"
# File to store the old IP address
IP_FILE="/home/fd/business/scripts/old_ip.txt"
# Read the old IP address from the file
OLD_IP=$(cat "$IP_FILE")
# Function to retrieve the IP address
get_ip_address() {
local ip_address
ip_address=$(curl -s https://ifconfig.me/ip)
echo "$ip_address"
}
# Query the API to get the current IP address
NEW_IP=$(curl -s https://api.ipify.org)
sleep 2
# Compare the new IP address with the old one
if [[ "$NEW_IP" != "$OLD_IP" ]]; then
echo "Your IP address has changed to $NEW_IP"
# Send an email notification
echo "New IP address: $NEW_IP" | mailto -s "IP address change" $EMAIL
# Allow overwriting of the file

# Update the old IP address in the file
# printf "%s" "$NEW_IP" > "$IP_FILE"

I think I use pam here. You may be using something else. Oddly, I don't recall seeing the one you said worked anywhere tho. So, it appears there is quite a few places that setting can be, even if google doesn't know it. lol Glad you got it working. That's what matters. Dale :-) :-)
