Custom MIME Types on Umbraco Cloud Resulting in 404

[warren (Warren Buckley)]

Hiya
Perhaps try with a PostConfigure in case something else somewhere when booting up overrides or changes the values set for the StaticFileOptions.

This helped someone out who had a similar problem

Using custom media types with blop storage (vtt, webm, webp, ogg, etc)

Well, @warren came to the rescue with this solution. Add to program.cs var customContentTypes = new FileExtensionContentTypeProvider(); customContentTypes.Mappings[".vtt"] = "text/vtt"; services.PostConfigure<StaticFileOptions>(opt => { opt.ContentTypeProvider = customContentTypes; });
