Failed to initialize honeywell client

My honeywell thermostat doesn’t work from this morning. The log said:

I’m sure the configuration is right. It worked well before today. But I still can use Honeywell - My Total Connect Comfort to control the thermostat.

same here, I think they’re having some API issues… just started yesterday for me

Maybe they changed the API.

It’s working right now.

There must be problems on the Honeywell servers. Today they sent an email stating that they are investigating on some service slowdowns and connection troubles.
