Hi,

I have recently upgraded a 7.5 project to 7.6, and fixed the various issues which arose from model properties now returning strongly typed values.

I'm now getting 404 errors on all the media library URLs, even though there is a valid media URL written out to the page.

We're using Azure BLOB storage & have the provider configured. I can see the images listed in the media library (and thumbnails load correctly).

For example in the razor script I'm using this:

@Umbraco.GetMediaUrl(Model.MainImage)

Where MainImage is an IPublishedContent. This invokes the following extension methods:

        public static string GetMediaUrl(this UmbracoHelper umbracoHelper, IPublishedContent content)
    {
        if (content == null) return null;
        return umbracoHelper.GetMediaUrl(content.Id.ToString());
    }

    public static string GetMediaUrl(this UmbracoHelper helper, string mediaId)
    {
        var media = !string.IsNullOrEmpty(mediaId)
            ? helper.TypedMedia(mediaId)
            : null;

        var mediaUrl = media != null ? media.Url : string.Empty;

        return mediaUrl;
    }

In the page output I get this:

<figure class="col-md-6  featured-content__image" style="background-image: url(/media/1506/some-friendly-image-path.jpg)"></figure>

And the path is correct (used to work before the upgrade) - but now I get a 404.

Any idea how to go about tracking down the issue?

Thanks
