Answer 1

It mostly is is a security related problem with your Access Control service rather then platform specific because there is no code change.

Have you changed any certificate recently which cause this service to break? Check your certificates or anything that depend on security because if you haven’t changed any code then changes in security setting could be the cause of your problem.
