Site has issues maybe DNS or CSS or who knows

Hi i am having problems with i think the is working correctly all images are showing at the moment im not sure whats going on as without the www. some of the icons are not loading and as well as on mobile not loading.

Wondering if its a DNS issue or a record i need to add im stumped it seems fine on my laptop but on mobile loading without the www. has issues it used to be the other way around without the www. was fine.

Would love both to work ?
Any suggestions or ideas highly appreciated
