Description

Steps to replicate the issue (include links if applicable):

What happens?:
The SVG image is not displayed where is is supposed to and only shows the file name. When clicking on one of the PNG previews, it returns with the text

"Unauthorized
This server could not verify that you are authorized to access the document you requested."

When attempting to view with the Media Viewer, a similar error appears and the image is not displayed. Links to the image used throughout Wikipedia are broken and only by viewing the original file are you able to see the image.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia): MediaWiki 1.44/wmf.8

Other information (browser name/version, screenshots, etc.): This error presents regardless of browser or skin used.

Also happening for https://commons.wikimedia.org/wiki/File:Hypercubestar.svg used in 30+ articles spread over 14 different-language Wikipedias. Re-uploading and purging did not help. See start of a discussion at https://commons.wikimedia.org/wiki/Commons:Help_desk#SVG_image_claims_its_thumbnails_are_unauthorized

There is some discussion of the first broken image in this report at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Broken_icon

  • Clicking on the PNG previews displays an error

Hmm, for the small rendered preview at https://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Gnome-colors-list-remove.svg/72px-Gnome-colors-list-remove.svg.png I Cannot reproduce, displays correctly for me. Using "Open in Media Viewer" on https://commons.wikimedia.org/wiki/File:Gnome-colors-list-remove.svg also works correctly here. Accessing those from Europe.

Aklapper renamed this task from Icon is not visible and returns an error when attempting to view as a PNG to PNG thumbnail of SVG file not displayed; returns "Unauthorized" error when attempting to view.Jan 6 2025, 7:44 AM

Discussion at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Image_Preview_Issue for https://commons.wikimedia.org/wiki/File:2020_Buick_Regal_Sportback_(United_States)_front_view_(cropped).jpg (screenshot https://commons.wikimedia.org/wiki/File:Image_glitch_on_Buick_Regal_wiki_page.png) suggests this is user-dependent: some people are seeing the problem and others not. I can see the Buick image thumbnails, for instance.

It looks like not just SVG files are affected as others are having the same problem with a JPG file from this discussion here. https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#Image_Preview_Issue

I went looking at swift, and e.g. the Buick thumbnail is correct (and identical) in both clusters.

The discussion was a little hard to understand, but it looks like they were talking about this thumbnail: https://en.wikipedia.org/wiki/File:Buick_Regal_2_--_10-30-2009.jpg
I have the same problem but when I click on the JPG previews of this file, I can see them. But I can't see it in the article.

I'm on the west coast of the USA if its a localized problem.

MatthewVernon added a comment.Jan 6 2025, 10:22 AM

So that's https://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Buick_Regal_2_--_10-30-2009.jpg/280px-Buick_Regal_2_--_10-30-2009.jpg - can you see that image OK?

Because it's in both swift clusters OK, and isn't a new thumbnail:

No I get the same error on both my main computer and my phone.

MatthewVernon added a comment.Jan 6 2025, 10:40 AM

Can you get your browser's developer tools option to dump the request, please? That should give us the HTTP status code (and ideally the full headers of the request), which might help explain where this error is coming from...

MatthewVernon added a comment.Jan 6 2025, 10:42 AM

(if you're using chrome, I think this stackoverflow article may help)

I'm using firefox but that's what it spit out.

Hm, this isn't correct

root@ms-fe2009:/home/mvernon# swift stat wikipedia-commons-local-thumb.f8
Container 'wikipedia-commons-local-thumb.f8' not found

So in codfw I can stat objects in the f8 container, but not the container itself(!)

@Cyberdog958 I think this should be resolved now. Can you try again, please?

Cyberdog958 added a comment.Jan 6 2025, 1:17 PM

Yes it is now working on all my devices. Thanks for the fix.
