Wow, you are right. Seems to be working right now. Thanks for reporting this :D

Sry, unfortunately this is not fixable. Crunchyroll blocked this method completely now, only way to see US Anime is using a VPN now.

Crunchyroll seems to have changed something on their side. Look at this Add-ons description for more info.

Edit: Happy it works for you again :) Enjoy your shows!

This should only happen when the extension cannot reach any of the API Servers. For me it looks like it's running (again?). Could you please try it once more? If it still doesn't work I'll try to find a solution to this.
