Connection Failure with Yggdrasil AuthServer Configuration

[sandsculpture233]

Hello MCC community,
I’m relatively new to networking and programming, and I apologize for not having the technical expertise to fully troubleshoot this issue on my own.
I’m encountering an issue when trying to connect to a Yggdrasil authentication server using the Minecraft-Console-Client (MCC). Here’s my current configuration:

AccountType = "yggdrasil"
AuthServer = { Host = "https://littleskin.cn/api/yggdrasil", Port = 443 }

Despite setting this up, the connection consistently fails. I suspect the Host URL might be incorrect, but I’m unsure how to troubleshoot further.
But confirmed my account credentials are correct and work on other clients.

Environment:
MCC Version: [MinecraftClient-20241227-281-win-x64]
OS: [Windows7 sp1]

Thank you for your patience and help!
