Tuya IOT API broken?

I had tuya working correctly up until a couple of days ago. Then, for some reason the integration has completely broken. For reference, I have tried the following.

-Double checked that my cloud API setup was correct.
-Changed app login password
-unlinked and relinked app to cloud API
-Removed and reinstalled Tuya integration.

The bulbs work fine on the Tuya app, and are showing up in the cloud device list. But when I try to set up the integration, all I get is “An unknown error occurred.”

Any ideas?
