HassIO on ProxMox - Error Connecting to HomeAssistant Cloud

Hello, I’m really new to Home Assistant, HassIO, and HomeAssistant Cloud. I have a HomeAssistant Cloud account…
I have recently installed HassIO on my ProxMox server and it’s running great. I’m slowly configuring different options and confiigurations… and I’m running into a problem with HomeAssistant Cloud where it just tells me “error connecting” and will not allow me to sign in.

Any Idea how I can resolve this issue? I really want to integrate my Alexa Account and Services into my Home Assistant Instance!

Any help would be greatly appreciated!

V/R,
A Noob with Home Assistant!
