Hello,
I'd like to report that thumbnails of files uploaded to idwikimedia throws 401 Unauthorized, see https://id.wikimedia.org/wiki/Berkas:Test.png for example and its https://upload.wikimedia.org/wikimedia/id/thumb/d/d9/Test.png/640px-Test.png thumbnail URL. It seems like problem that appears because it is a new wiki, when I tried to upload the same test screenshot to cs.wikipedia, it was working with no problem.
I'm going to keep this test file live until this problem is solved.
Thank you in advance for fixing,
Martin Urbanec
