Error communicating with server

Hello, I have just downloaded Anki (2.1.35 for mac OS X 10.10.5), but once I opened it and tried to sign up, an error chart popped out:

My web browser is working just fine, so I clicked on “Help” down on the Anki app in order to contact support and another error popped out.

Could you help me figure out what is wrong? Thank you! Lucie

Thank you :slight_smile:
