When printing out of a web app using the print widget, I most often get the error "Unable to load //utility.arcgisonline.com/arcgis/rest/services/Utilities/Printing/Tools/GPServer/Export%20Web%20Map%20Task/execute status: 0". I can occasionally get a few prints, but then consistently get the error. I can reboot my machine and sometimes get a few more prints, but not consistently. This is happening using Chrome, Firefox, or IE and, further, I'm getting it happening on two different machines. It also happens with similar, but different, web apps.I'm totally at a loss to figure out what's going on here.
Does anyone know if this issue was ever resolved @KellyGerrow ? We just started seeing this pop up again when we would use the Force Scale option to print a certain view. The suggestion above from @ClaudiaGIS seems to work in fixing this temporarily.
