I've noticed that scrobbling to last.fm stopped working for me on my mac desktop client (behind a corporate proxy). It worked well just a couple of days ago.
Removing access to the last.fm app and reconnecting it didn't help. Restarting the desktop client didn't help either. What to do?

BTW, your reCAPTCHa is VERY annoying (green check "I'm not a robot" and then "Verification failed." 6 times already??!). See also https://news.ycombinator.com/item?id=20147015
