403 error code: HTTP Forbidden

The HTTP 403 Forbidden status means the server understood the request but refuses to fulfill it; the status alone may not explain why.

Plain-language meaning

What HTTP code 403 means

RFC 9110 defines 403 Forbidden as a response where the server understood the request but refuses to fulfill it. A reason may appear in the response content, but the status itself does not specify one. RFC 9110 adds that if authentication credentials were provided in the request, the server considers them insufficient to grant access, and that an origin server wishing to hide the existence of a forbidden resource may instead return 404 Not Found.

Keep the code in its namespace

What this code does—and does not—tell you

HTTP 403 is a protocol status. It is not automatically a Roblox client error, an invalid-password message, or proof that an entire site is offline. The server may refuse a request for reasons unrelated to credentials. It also differs from 401 Unauthorized: 401 signals that authentication is required or has failed, whereas 403 means the server refuses the request even when the client is authenticated.

Conservative next step

Where to check next

If you are visiting a site, read any explanation shown with the response and use that site's official support channel if access should be available. If you operate the service, inspect the request and access policy; RFC 9110 says clients should not automatically retry with the same credentials.

Same number, different meaning

HTTP 403 is not every “403 error code.”

For example, Roblox has a separate 403 entry. Compare only after confirming which system produced the message.
