Help with chrome

I set it all up, on Mozila works fine, sends notifications too.
On Chrome, the notification to subscribe shows up, i agree and that’s it, i get no notification, also the Subscribe button doesn’t work.

I see a waring in the console i need to serve the sdk file straight from my domain, i use W3 total cache with own cdn setup on different domain: cdn.xxxx.ro. I have no option to exclude these files from loading over that CDN in W3 total, any ideeas ?

I set it up using the HTTPS guid sdk install guide to test it, and it works just fine, but if i leave it like that will a notification on new post be sent ?

buzaupress.ro is my site.
