Tuya IoT setup failure

I am new to this (i know another noob) but it is supposed to be easy. I want to add the tuya integration to a fresh installation. So i follow good old youtube, setup an account on the auth.tuya.com and set a cloud project, i select the device status authorisation and complete.
so far so good, next the guide says to go to device selector to add your app… heres where i get the glitch, instead of getting the page, every single time i get some chinese message that says oops…
has anyone come accross this as it is very frustrating, all the tutorials say the same thing so they look good just… nothing.

I used this one which worked for me. Posisbly you have to select the proper data center?
Do note that Tuya changes their IoT-site over time
