I am unable to find anything on how to get the Product News and OTRS news working, I'm receiving the below error:

Can't connect to: http://otrs.org/product.xml (500 Can't connect to otrs.org:80 (connect: Network is unreachable))

I am using OTRS 2.4.4 on linux Suse.

Can anybody please tell me what I have to do to get this working?

Thanks
