Google Home error

I noticed in my log an error with Google Home.
syncResponse Error: null, giving up for now
And also: tokenResponse Error: null, retry count exceeded, giving up for now.

When I try to reconnect using google home, I get this error:

The parameter "state" must be set in the query string.

Do I need to unlink and reconnect?

I had rhe State error fairly frequently and also had Hubitat cloud issues. I've not had them since I migrated my hub though.

All my GH switches would stop and I could not re authenticate my GH connection.

The temp fix for me was to reboot my hub, perhaps if that didn't work a full off and disconnect. If that didn't work then a router/network reboot.

Reboot fixed the issue. Thank you.

If you continue to have loss of cloud connectivity in Hubitat, it's a known problem right now.
