How to Fix a Failed Download

Double-check the URL

Make sure you copied the full URL from the address bar. Shortened links should be opened first, then copied from the resulting page.

Check the video status

Deleted or private videos cannot be downloaded. Confirm the video still plays normally on CZK first.

Check for age restrictions

Age-gated videos require a premium account and Naver authentication cookies.

FAQ

Download Error FAQ

VOD Loader: FAQs

Check, in order: is the URL correct, has the video been deleted, and is it age-restricted content. Most failures come down to one of these three.

Once a video is deleted from CZK, we cannot recover it. Popular VODs are sometimes proactively archived before deletion, so a download may still be possible if it was cached in time.

We use parallel HLS segment downloading which is generally fast, but speed can vary with your network conditions or server load.

General: FAQs

Free accounts cannot download age-restricted content. Log in with a premium account and enter your Naver authentication cookies (nidaut, nidses).
