Amazon Connect Chat - Something went wrong

Hi All,

I am trying to test an Amazon Connect chat through a google site. When loading, I get the error: We’re unable to load chat at this time. Please refresh the page to retry, or try again later (400)

I have had a look at the following help: https://docs.aws.amazon.com/connect/latest/adminguide/ts-cw.html The domain https://sites.google.com/ has been added under domains and security within the settings for the Communication widget.

Not sure if I am missing something but if anyone can provide any further insight as to how I can resolve this that would be great!

Thanks, Rob
