This problem fixed for me with change my data center. When i select all data centers after scan qr code this error seeing. But a iam from Azerbaijan and when i am change to Central Europa data center this problem sloved for me.
THanks, this did it for me.
I’ve created a new password in the app: nothing. Then I’ve logged out in the IOT platform as you said, logged in again and IT WORKED. Thanks!
Fantastic, this worked for me too!
One more data point in fixing the issue caused by using google login.
Tuya Smart app doesn’t even have log out. I had to delete the app. Then revoke access from google.com to the app. Then when launching the app, go to forget password. Luckily, the app can’t know that you never had a password - so it will happily send you a password reset code to your email. Then you can use that to create a password. Then you can link tuya with home assistant.
Lesson learned: never use third-party login for things whose account you need to share with other system for integration.
