Why are my scraper requests failing with 403 errors?
I'm running a web scraping project, but suddenly all my requests to a specific e-commerce site are returning 403 Forbidden. How do I figure out if my proxy IP has been banned without manually testing each one?

A 403 error usually means the server has blocked your IP address or detected automated traffic. To determine if the target website has restricted your IP, you should test the address. You can easily use an ip checker blacklist https://proxy-checker.net/en/blacklist/ to find out if your proxy is on any major spam or restriction lists, allowing you to quickly replace blocked nodes.
