Q: itunes unknown error 11503

I have a Macbook Pro 2012 (not retina) running El Capitan.  Recently updated iTunes, running 12.4.0.199

 

Having errors accessing iTunes store at times & even accessing account.  Every time I do get into my account & try to download available downloads, it as an error. 

 

This error, 11503, is connected to when I try to purchase something & it will not go through.  Instead I get this unknown error.  Have tried searching for solutions, but all I can find are for outdated versions of iTunes and OS X (most recent I found was from 2013).

MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11.5)
