My Auth table doesn't exist

Since yesterday, my testing server facing this error:

This happen when I click “Login” on my webpage then it stuck showing “Verifying” and go no where.

I check on my database, no table named “_Auth” but in my other ERPNext instance, where the login works, also no “_auth” table. so why my testing server facing this error?
