+## Description
+
+I get the `Failed to find a valid digest in the 'integrity' attribute for resource ... with computed SHA-256 integrity ...` error after upgrading Telerik.UI.forBlazor Nuget package in my Blazor WebAssembly and publishing the app.
+
+## Error Message
+
+>warning Failed to find a valid digest in the 'integrity' attribute for resource ... with computed SHA-256 integrity ... The resource has been blocked.
+>
+> Unknown error occured while trying to verify integrity.
+
+## Cause
+
+The error `Failed to find a valid digest in the 'integrity' attribute for resource ... with computed SHA-256 integrity ...` is a general Blazor WebAssembly issue, which can result from the build process, publishing process, or browser cache. The Telerik UI for Blazor components are not the cause.
