Error Invalid method name format when performing patch data import for redhat

Hi

I am currently trialing Altiris and attempting download the patch data for Redhat linux. When I click import channels on the patch management page I get the error: failed to connect to red hat server network....invalid name format.

When i go into the site directly I am able to sucessfully login. When i initally ran the channel import it ran sucessfully however i was then unable to run the full import of patch data. Now I can not even run the channel import.

Does anyone have any ideas as to what could be causing this??

Thanks
