Server error when trying to get builds Windows insider

[ArrowQueen]

Hello everyone !
I'm having an error message in the Windows insider app when I click on "get new builds". I've been trying it for 3 days but still not working (see picture attached). The message says: "a connexion error has prevented us from downloading programs. Check your date and time on your device and your connexion, then try again" . I would really appreciate your help. Thanks
