Error: Faraday::ConnectionFailed. Message: Failed to open TCP connection to res...443

Question

Hello! I can't finish the trailhead due to the next error: There was an unhandled exception. Please reference ID: XNOIWBUC. Error: Faraday::ConnectionFailed. Message: Failed to open TCP connection to :443 (getaddrinfo: Name or service not known) Moreover, can't check any other modul in this DE Playground: :( It happened after changing My Domain to the next: consultkiev-dev-ed-dev-ed I'd waited for 6 hour than checked again - the same error... Have any idea on this issue? Or it's better to create new DE Playground (is yes - HOW?) and don't change My Domain? Thank in advance!
