On Localhost my Validation for a user's billing address works, before its submitted. Once I pushed the project to production. Validation does not initiate and I receive the following error "Sequence Contains no Elements . It points back to my Controller "model.Address = db.Addresses.Where(a => a.AddressId == model.AddressId).Single();".
Screenshot of the code causing the error

I'm guessing you're seeing error thrown here:
model.Address = db.Addresses.Where(a => a.AddressId == model.AddressId).Single();
Try .SingleOrDefault().
Also check if db.Addresses is not empty
if (model.Address != null && db.Addresses.Any())
EDIT: try this
model.Address = db.Addresses.FirstOrDefault(a => a.AddressId == model.AddressId);
EDIT2: only assign model.Address with existing address if it's not a new address:
if (model.AddressId != null && db.Addresses.Any(a => a.AddressId == model.AddressId))
model.Address = db.Addresses.First(a => a.AddressId == model.AddressId);
