Hi Chris thanks for your efforts! But at the moment the server is unreachable 
http://wxd.weather-watch.com/wml_sys/wxsim_gfs_data.php?lat=40.89&long=16.85
Just tried to download the data with WXSimate and still getting that the GFS & GFS for Advection is not accessible, Chris.
Thanks for that. Might be a DNS or web server issue. I’ll take a look ASAP.
Same here Chris

Now it seems to work again! 
I think it was a DNS problem (the new server has a new IP address). The records have updated for me now so hopefully you should all start to see the change soon.
Looks good here too
