This ERROR CODE 4 malarkey has been going on for ages !!. I have followed all the remedies and solutions but to no avail. I do observe, however, that there does not seem to be any input from a Spotify operative. Excuse me ,Spotify, this is a paid for service !!. You really need to make an effort in trying to resolve the error code 4 problem !!. I am sick and tired of paying for a broken service !! Get it sorted .... !!!!
This solution does not work for those working off office provided computers that have administrative locks. I am unable to access the connection properties because I need an administrators login and password.
