Hi, I'm trying to upload a cropped screenshot of a game on my phone, but all avenues give one or another kind of error.

With visual editor I just get a small pop-up saying "An unknown error occured."

In classic editor, i get "File type verification error!"

I tried using Special:Upload, which gives the error: "This file did not pass file verification."

The file is .png and about half a MB, file name does not have any special characters, so I really think it is within limits of what is considered appropriate.

I am using up-to date Mozilla Firefox, if that's relevant.

Has anyone have any ideas what could be wrong and how I could possibly troubleshoot this?
