Problem with my Colab RDP

Hi there,
Today I have been encountering this error in many devices and with my 3 google account. I make a colab RDP but then I can’t sign in to it. It shows please try again in a minute but never work.

same problem here

Are you connecting to the same RDP or different?
I’m pretty sure RDP’s only allow one user per session.

I think they patched the RDP method. The RDP method is no longer work in google colab.
