Can't add "LogicMachine"-device on Google Assistant/Home

[PolymorphedCust]

I tried setting up Voice Config and Google Home App for LogicMachine. But at the step of adding the LogicMachine to devices to help Google Assistant/Home if fails. The very first time it asked for a Log-in, I used the "Log-in via Google-account"-option, and ever since it's been coming with this error. 
Anyone knows what this is about, and how to fix it?  

Best regards,
