Hello @Weidan Deng and welcome to Microsoft Q&A.
I have seen this error message after enabling the internal-only scope feature. I do not know what a torus account is. Please let me know if the scope feature is not involved. As this is an internal-only feature I cannot share the solution publicly here. I will reach out to you via other means.
EDIT: due to demand, here is link to TSG (MSFT only)
