I run this little script to notify me when the IP changes. However

What could be causing it?

EMAIL="your_em...@gmail.com"
# File to store the old IP address
IP_FILE="/home/fd/business/scripts/old_ip.txt"

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.
sleep 2
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?
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.
