Why is my IP address detection tool suddenly failing?

My 'What is my IP Address' tool is completely broken and I'm losing my mind trying to fix it. For the last few hours, it's either showing an incorrect IP or just getting stuck during the IP address detection process.

It was working perfectly fine yesterday, and I haven't made any major code deployments or server changes. I've checked server logs, reviewed recent network configs, and even restarted the service multiple times, but nothing seems to help. Users are reporting either a generic ISP IP or no IP at all, which makes the tool useless. What could possibly cause such a sudden and critical failure in IP address detection? Any specific server-side or network-level issues I should be looking into right now?
