Hey everyone,
Since recently the animation on Vox Codei (hard) isn’t working for me anymore. It doesn’t prevent me from testing my code but without a graphical output it’s kinda hard to see what’s going on.
I tried other puzzles and had no problem with them.
Picture of how it looks like : http://tinyurl.com/hm6bh84
I’m using Firefox 44.0.2
Edit : I just looked at Vox Codei (very hard) and the same problem occurs
Can you open the console (F12) and refresh the page? Any error message could be useful to us. I can’t reproduce…
Here it is (partly in French, I don’t think you mind 
)

That’s the error I suspected… “missing Access-Control-Allow-Origin”. We have troubles figuring out the cause of that problem, we use Amazon S3 and the configuration seems valid.
You can try with a different browser, maybe it will work. Usually that issue disappear by itself.
I thought some of my ff addons were interfering with that failed request so I tried with Edge, but the problem occurs too 
And it was working fine just 2 or 3 days ago.
Also I don’t have any problem with the other puzzles, looks like it’s specific to this one.
Ok not sure what to make of it but maybe that will help you : I used a vpn to change my ip, and the problem disappeared. Now if I disconnect and go back to my normal ip, it’s broken again.
I’m not surprised and that’s why it’s difficult for us to investigate… When asking for a file, amazon may not use the same server to serve the file and that server doesn’t send the header that is missing.
Looks like you’re not the only one having that problem : http://stackoverflow.com/questions/17533888/s3-access-control-allow-origin-header
At least a vpn can be used as a temporary workaround, good luck in your work
