Custom URL destination block lists allow Umbrella to extend a domain level block list to encompass full and partial URLs. In turn, this allows you to block certain portions of a website based specifically on the full or partial URL. However, there are limitations and it's possible that the configuration of your destination lists might result in error messages.
NOTE: The feature described in this article is currently not available for most customers and is in early release. For more information, please read: https://docs.umbrella.com/product/umbrella/custom-url-destination-list-how-to
For more information about guidelines that must be followed to ensure that the URL you are entering is actually the one you want blocked, see Custom URL Destination Normalization
|URLs in allow lists are not currently supported. Consider adding the domain only instead.||You'll get this error message if you add a URL to an allow list. Remove the URL and replace it with the domain for that URL.||We are considering adding custom allowed URLs in the future. Please submit a feature request if you would like to see this feature added to Umbrella.|
|Please check to confirm that the URL was entered correctly.||There was a problem with the URL, either in the domain, path or query. Review your URL for legal characters and URL composition. Additionally, you may enter a partial URL to leverage right-side wildcarding. For more information, see Custom URL Destination List How-To.||We adhere to RFC-3986.|
|The supplied URL belongs to a domain that does not present a security concern but may impact Umbrella performance if proxied. Consider adding the domain only instead.||URL matches the high-volume domain list. Consider blocking the domain if you don't trust the destination.||High volume domains do not present a security risk themselves and do not require additional scrutiny.|
|The supplied destination matches the Umbrella global allow list and cannot be saved.||The URL matches the protected allow list. Consider blocking the domain if you don't trust the destination.||Destinations in the protected allow list either host services other than HTTP and cannot be proxied or are critical to Umbrella operations.|
|Only ASCII characters can be used for defining URLs.||The URL contains non-ASCII characters. Try percent-encoding the URL or block the domain.||The Intelligent Proxy currently does not support non-ASCII characters. Please submit a feature request if you would like non-ASCII characters supported in Umbrella.|
|There was an issue with one or more of the destinations in the uploaded list.||This is a bulk upload error message. One or more of the URLs supplied in the uploaded list match one of the error conditions above.
Umbrella should provide you with a link to download a list of destinations that could not be uploaded. Please correct or remove the destinations from your bulk upload list and try again.
|Umbrella will not write uploaded destinations to the database unless all uploaded destinations can be accepted.|
|Invalid destination.||No action can be taken at this time. This is a generic error message.||The supplied destination cannot be accepted by Umbrella. You have encountered an error condition Umbrella cannot account for. Please log a case with support so that we can address this error condition.|
