Aklapper renamed this task from File doesn't show, network tab of browser shows 429 error to Thumbnail for 50MB TIFF file not shown: HTTP 429 error.Sep 2 2019, 7:48 AM
Aklapper edited projects, added Thumbor; removed Wikimedia-production-error.

The file itself is shown; its thumbnail is not shown. :)
@Mbch331: Adding Thumbor as this is about thumbnail generation; removing Wikimedia-production-error (see its description).

'Too many requests' just means that throttling is being applied, because the attempt to generate the thumbnail failed too often in a row. Probably the thumbnail renderer is running into memory limits.

This is a huge Tiff image btw. Is that supposed to be the entire book ? Because in that case, the tiff is missing important markup information that lists the various pages. That would explain why the software doesn't recognise it as paged and has trouble rendering it.

I think this is an upload by @Nemo_bis, maybe he can help figuring out this file.

The Tiff contains a single uncompressed bitmap, 3668 × 4660 × 3 = 51MB.

@Bdijkstra i tried compressing it in Preview.app and then it turned into 64MB, Thats what made me suspicious if this really was a single page. ;)
