No, It's Not a CORS Error
summary
Explains the web security mechanism behind Cross-Origin Resource Sharing (CORS): what triggers the browser message “Cross-Origin Request Blocked,” why Access-Control-Allow-Origin may be present yet errors still occur, and how to distinguish true CORS issues from other causes. Covers the purpose of the CORS mechanism and common situations where the visible error is misleading rather than an actual CORS problem.
