Print Widget problem esriJobFailed

Hi everyone, i would appreciate so much your help with this issue. I have published my web page with Print Widget as one of my toolsand it works fine when im inside my LAN, but when i run the Widget from any other location outside my network, it throws :esriJobFailed, I've seen the process with Fidler and HttpWatch (Firefox) but everything seems to be fine: the urls and the job assigment.

Please someone who could help me with this problem,

Thanks a lot!!
