Enciclopedia de Códigos de Error

A comprehensive reference of 1360+ error codes across 15 categories including HTTP, JavaScript, Python, TypeScript, Git, Docker, Linux, SQL, and more. Each entry explains the cause and provides a fix.

Use the page search field for an exact code such as 404, ECONNREFUSED, or TS2304. You can also open the paste box and paste a full diagnostic message to extract every matching code automatically.

Each fix is written based on official documentation and common developer experience. We link to official documentation for every error code so you can verify the information.

Yes! Use our comparison feature to see side-by-side differences between commonly confused error codes, like HTTP 401 vs 403 or EPERM vs EACCES.

Start with the exact error code and full message, then note what you were doing when it appeared, the affected language or tool, and the smallest reproducible example you can safely share. This context helps you distinguish the root cause from follow-on errors.
