after giving acces and redirecting to blender this happens

[crecerhecer]

fix is easy, u need give access only to your account, and it will be ok, after that u can un-login in blender and login again, now u can give access to account and all groups u can

I suspect what you give access to does not affect this specific error, it was probably just the process of trying again after your computer's clock automatically synchronized itself that made it go through. This is a similar report to this issue: #17
