Home Assistant Integration

I am trying to integrate a new install of Home Assistant (mostly just to play around with to see if it can offer me anything that ST can’t) and I am running into an issue.

I have created an access token for ST and when I try to enter it into Home Assistant I get this error

I have been using ST for a while and it has about 60 devices attached to it, I have just installed Home Assistant and done pretty much no configuration of it, I used the automated install so all the standard config will have been done during the install. I have Home Assistant running in a Docker Container in my home NAS (QNAP), it runs ok and sees devices that are on my network that ST cannot see, so I can assume that the default config is working OK. However this error really is getting to me and no matter what I do I cannot figure it out.

Any help would be greatly appreciated.
