I am having the same issue here in the US
+1, I’m new here and want to get started learning Unreal, but it seems there’s a ReCaptcha error with the learn subdomain.
Yes, I have the same issue too. I tried to change my password, connect on a different VPN server changing browser from chrome to explorer… Nothing changed. I am from Quebec, Canada.
Same here from Ukraine
It seems to be working now! 
Seems to be back up now, at least in US and Canada. Judging by the error in the bottom right of OP’s screenshot, Epic probably forgot to update an API key before it expired. It’s unfortunate that this happened at least both in February and April 2020 (which I assume were two separate instances).
