Cannot login in Nest chrome simulator


We had a working account which yesterday stopped working.
Today we create a new one. It worked for only 10 min and stopped working.
We can not login to the Simulator anymore.

We can login to by that emails but not in the Simulator.

What we tried:

  • delete simulator extension and install it again
  • delete the cache of chrome
  • tried on a new system

Hope you can help us.
