Warning on Live Site under images…just went live/no problems before

Hello.
Everything was working fine until I went live. I love this widget and want to make it work. The WP site is hosted on Go Daddy.
The error message: Warning: getimagesize(https://laughingdogbicycles.com/wp-content/uploads/2015/07/e65a2b479516cae1bbe71f89d01fa5fb.jpg): failed to open stream: No route to host in /home/content/p3pnexwpnas08_data03/08/2653608/html/wp-content/plugins/really-simple-image-widget/really-simple-image-widget.php on line 88

Go Daddy tech help suggested deactivating and deleting and reinstalling. I did this but did not help. I tried correcting the image sizes to fit the reqs for thumbnail, medium, and large, but realized this widget doesn’t require that (does it?).

Other support strings suggest that I delete line 88. Any suggestions?

The site is: https://laughingdogbicycles.com/

Thank you!
