New security measure preventing IP return

[Justinzobel]

When using via curl I got ifconfig.co needs to review the security of your connection before proceeding. among other HTML returned instead of my IP.

I am having the same issue. Looks like Cloudflare is causing it. If I call https://ifconfig.co/country-iso from my site hosted on Netlify, instead of returning the country ISO value it returns this HTML code:

It was first noticed on one of my sites around 17 November 2022.

I'm seeing this as well. I want to add that on my network there is only one service polling for IP changes, once every two minutes. This is within the requested limit of 1 request per minute described on the website.

Seeing the same issue while running the command from the front page.

I just noticed the same issue on an EC2 instance. I suspect this service is probably provided for free, so I can't imagine there's be much appetite for disabling captcha.

Nice one, thanks!

Another alternative (using https, in case port 53 is blocked):

curl api.ipify.org

[hydrargyrum]

Yes, ifconfig.co is worthless via curl, but api.ipify.org works fine!

[TheKigen]

It is just a security setting that needs to be changed on the CloudFlare account running ifconfig.co. I setup ipcfg.co as another. Though other than the front end its entirely rewritten to just be a CloudFlare Worker.

Another alternative for curl and tor users

curl ifconfig.la
