• Problem with running code? 502 (Bad Gateway)

 

I don't seem to be able to run code — the three square animation just plays forever, and the console displays the message:

POST https://py.checkio.org/center/1/run/ 502 (Bad Gateway) send @ jquery-2.2.4.min.js:4 ajax @ jquery-2.2.4.min.js:4 sendRun @ app.js:590 runCode @ app.js:1344 (anonymous) @ app.js:1348 dispatch @ jquery-2.2.4.min.js:3 r.handle @ jquery-2.2.4.min.js:3
