What each QR code error page means, from "QR code not found" to "This campaign has ended", and how to fix it.

When a dynamic code can't open its destination, scanners see a short page. Here's what each one means.

## "QR code not found" [#qr-code-not-found]

This is a 404 page: the short link doesn't belong to any code.

- The code was **deleted forever**.
- The code's **back-half** or **domain** was changed after it was printed.
- The account that owned it was deleted.
- The link was typed by hand with a mistake. Short links are case-sensitive.

A deleted code can't come back. If you changed the back-half, change it back with **Edit link**.

## "This QR code is no longer active" [#this-qr-code-is-no-longer-active]

The code is **archived** or in the **trash**. Choose **Unarchive** or **Restore** in **Codes**. See [Archive, delete and restore codes](https://qrdx.dev/docs/help/dynamic-codes/archive-and-delete).

QRdx also turns off codes that link to harmful sites.

## "This campaign is paused", "hasn't started yet" or "has ended" [#this-campaign-is-paused-hasnt-started-yet-or-has-ended]

These come from the code's own settings: a pause, a start or end date, or a scan limit. Change them in **Access & schedule**. See [Pause, schedule or limit a code](https://qrdx.dev/docs/help/dynamic-codes/pause-schedule-limit).

## "This QR code is password protected" [#this-qr-code-is-password-protected]

The code has a password. Enter it and click **Continue**. See [Protect a code with a password](https://qrdx.dev/docs/help/dynamic-codes/password).

## "Too many requests" [#too-many-requests]

One network opened a lot of QR codes in a few seconds. Wait a moment and scan again.

## "This domain isn't connected yet" [#this-domain-isnt-connected-yet]

The code uses a custom domain whose DNS setup isn't finished. Check the domain on the **Domains** page in your dashboard.

## "This page could not be found" on a page [#this-page-could-not-be-found-on-a-page]

A mobile page at `/p/…` shows this when the page was deleted or the address was mistyped.

## "This form isn't accepting responses right now" [#this-form-isnt-accepting-responses-right-now]

The workspace reached its monthly form response limit. See [Collect answers with a form](https://qrdx.dev/docs/help/pages-and-forms/forms#monthly-limits).
