@JeppeK16603117 Hi Jeppe, as noted in the error message, there seems to be an issue with your network connection. Check your network connection to ensure it is functioning.

Also, if you are on a VPN, try disconnecting from the VPN. If you are on a corporate network or proxy server, it could be the firewall/security settings - try attempting the challenge from a different network.
