Screenshots that failed to capture display our 404 - Page Not Found placeholder image.
These screenshots are excluded from your monthly usage count and thus not charged for.
The reason for the unsuccessful snapshot is probably one of the following:
The URL may point to a page or domain that no longer exists.
Please verify and change, pause or delete this URL from your account.
We only capture regular webpages. If the URL points to a different file type (like PDF, TXT, XLS, DOC, etc.) it will fail to capture.
You should change, pause or delete this URL from your account.
If the website does not allow crawlers and bots, it may be getting blocked by the WAF (web application firewall).
For possible solutions, please check the article: Why am I getting "Access Denied"?
There may be an incidental cause, like maintenance on the website you capture, a disturbance in the network or a glitch. This should happen only once in a while; if it happens more often, it's likely one of the causes mentioned above.
