Jetpack Stats Image in Admin Bar Broken

At some juncture (a while back, I can’t remember when) the stats image on the admin bar of my site http://www.daveenjoys.com became broken – and it has never worked since – in spite of several upgrades to both wordpress and jetpack.
The rest of the stats works fine – when I click on the broken image it takes me to the stats dashboard and displays the stats without issues.
I run a number of sites – some on this same virtual private server – none of the other sites have this problem.
