Q:

Imgur error: "Failed to upload image; an error occured at imgur"

I can't seem to upload images. I've tried a few times over the past hour or so, with no luck. I tried uploading an image that I've previously added to an answer with no problem, and tried in both Chrome and Firefox, but no joy. Also tried on another SE (I'm posting here because this is the main site I use).
I can drag and drop the file to the Imgur window fine, but when I click the "Add picture" button I keep getting the same error ("Failed to upload image; an error occured at imgur"). It even happened when I tried to "provide a link from the web" with the link to an image from an ELU post hosted on Imgur itself.
(I'd post a screenshot of the error message, but...)

A:

Unfortunately I can't reproduce the problem. I'm having no trouble adding a picture.
