Works on Raspberry Pi, but not on Mac

[petebocken]

The script has worked perfectly fine for almost a year on a Raspberry Pi. However, when I run it on my Mac mini (macOS 13.6), it runs fine with no errors, but does not update the Cloudflare DNS entry. I am simply copying the same exact script file over.

The Pi and Mac are on different subnets, but nothing should be getting blocked on the Mac.

Output of bash -x ./script.sh
